I will start by saying that I am by no means an authority, and that you are free to ignore my advice or take it as you will.
With that said, I think the piece overall as a whole is very strong and that you tackled the subject pretty well considering that green is one of the hardest colors to work with. Now, the reason I deduct points for originality is because the whole motif of "the mysterious ___ looking over the ___" has been done a lot, although I did give you a little bit back for the interesting perspective.
Now, I am going to focus on the actual critique and advice here, which you are free to ignore or agree with as stated earlier. I would suggest pushing the perspective further and really emphasizing curvilinear perspective which compositionally would've framed the shot better. Some fundamental things like atmospheric perspective and depth of field would've really sold the shot too, things tend to lose detail and edges become more lost as they recede in space. That would've helped put the needed focus on Zecora, and changing her shroud would have probably helped as well since green on green is very tough to spot. Going back on color, I will again give you applause for working with green since it's a very tough color to work on. Of course, that being said, some of the foliage could have used a bit more variation in hue and saturation, as not all plants are so close in hue as depicted, even grass has lots of variation within itself. I also would've liked to see the poison joke being used more to tell a story. How it recedes into the distance almost works but it isn't strongly defined enough to be obvious whether it's a key story element or just more background detail.
I'll end this restating that I do think it's a pretty strong piece and that you should feel very proud of the end result!
Two words; Depth and magnitude. That's what this piece brings to the table, depth and magnitude. Everything about it seems to be so huge and vibrant, I really have to look for what to criticize. Now, I'm gonna have to respectfully disagree with my fellow critic who reviewed this one. I might not be an artist, but I damn sure know when an artist's design works and when it doesn't. He/she said that changing the perspective of this piece or shifting the focus to Zecora herself would have made it better. That I can't agree with. With the audience is given a perspective such as this we are forced to be in the same shoes as the character herself. The artist does a fantastic job illustrating the sheer size of the tree trunk in front of her and how it towers overhead, as well as leaving enough room for the surrounding trees and the sunlight that pours in from between them. From this perspective we get to share in the sheer magnitude of the forest much like our zebra friend, and take in the depth and atmosphere just as she is. It just offers so much in the way of wonder.
Now, as far as what I believe could be "improved." There were only select few places where the colors seemed to run together. A forest is full of lots of green upon green, but the artist did a very nice job separating most of the plants and leaves with different shades and lines. The top of the hollowed out trunk has some moss hanging off of it, and the colors of the leaves above them seem to kind of run together with them. Sure, sometimes the trees seem to blend in with the grasses and surrounding plants, but, hey, have you ever been in a forest? Not every stick and branch is clearly visible among the brush in real life either.
All in all, one of my favorites. I might be just a little bias with this critique because it brings up personal feelings of nostalgia for me. It reminds me of the days hiking out in Philmont and beholding the wonders of nature on a daily basis. I especially love how the shawl Zecora is wearing blocks her eyes from the viewer. I know what her eyes show, how about you? Have you ever beheld such sights?
So long as you don't mind the answer in a rhyme, but given that the Everfree Forest seems to run on different set of rules then the rest of Equestria, it probably has many secrets. I like that you added a lot of details and made it seem that the forest kept going on and on ( up and over).
I really liked the second critique you got. This piece is gorgeous and immersive. I could get lost just staring at it. When I have the disposable income, I will ask that you offer this as a print. So awesome...
WARNING! Carry on reading! Or you will die, even if you only looked at the word warning! Once there was a little girl called Clarissa, she was ten-years-old and she lived in a mental hospital, because she killed her mom and her dad. She got so bad she went to kill all the staff in the hospital so the More-government decided that best idea was to get rid of her so they set up a special room to kill her, as humane as possible but it went wrong the machine they were using went wrong. And she sat there in agony for hours until she died. Now every week on the day of her death she returns to the person that reads this letter, on a Monday night at 12:00 a.m. She creeps into your room and kills you slowly, by cutting you and watching you bleed to death. Now send this to ten other pictures on this one site, and she will haunt someone else who doesn't. This isn't fake. apparently, if you copy and paste this to ten comments in the next ten minutes you will have the best day of your life tomorrow.You will either get kissed or asked out, if you break this chain u will see a little dead girl in you sorry
