Aquatongue hunts Wind Catcher

This is my most succesful drawing yet (that's what my art teacher told me). The two animals do not exist, and are based on Wayne Barlowe's animal (mostly the Aquatongue, based on the Arrowtongue). I must admit I am only an apprentice so I have no clue if this is illegal posting.
What I believe people admire most about this one is the details in the trees and the river bed. When I used to draw animals on blank paper I didn't give much but now that they're in the wild, I guess they became more alive.
