Anyway, thank you everyone.
You sure it's not firendly Chomper playing with Littlefoot? XD
Haha, it could be.
Now this is a unique entry for the prompt! Maybe you had some more ideas left over from the humanization one? I can honestly see why you would get frustrated with this one as the perspective it is drawn at is actually quite difficult. That being said, the general shape of Sharptooth here I would say is pretty good! One thing I would say for him is to widen his stance. Generally sharpteeth have their feet quite wide apart.
I think I recognize the pose of Littlefoot's mother from the movie. I find it can be difficult to use references from the first movie as the can hide a lot of detail in their shadows during some of the more darker scenes. If possible I would try to work on a side view perspective when starting out as it's generally the easiest to learn in my opinion.
I know the feeling of losing motivation on a current drawing, so I'm glad you at least were able to share the idea you had! Hopefully you'll have more motivation for the next one! 
Nah, this idea came to me after the humanization prompt. And yep, I was using the pose of Littlefoot's mother from the movie. Thank you for the suggestions.
I think by adding a line to indicate where the horizon is would help the drawing to look less "flat" as it would create a point of reference and orientation.
If you find some time and motivation again, you should definitely refine the drawing, the idea is honestly amazing! 
Thank you very much. Alas, I had already finished with this piece by the time I read your comment. But now that you mention it, horizons is something I would like to feature more often. I really like that idea. In fact, you may have just inspired me to add one to my next drawing.
But anyway, as it happens, I later found the motivation to get this finished after all. I decided to go with the "silhouette colouring effect" that I mentioned earlier. I realize that a few of the colours aren't entirely accurate, but I was just sort of experimenting, and going for a slightly surreal look.
