Yep it's based on the poster for The Hobbit.



Thanks for the flattering review, although I was looking for something a little more subjective so I could improve. As for the horn placement I could see what you mean about it being a bit too high. Some artists seem to put it at an angle so its below the top of the hair or have it pointing at a larger angle making it appear higher than the hair. Ears depends on the artist a bit, I haven't done an image where a pony is being viewed from behind so that view was new to me. As for the shadow I haven't tried that either so I kinda guessed at it.



Here is one error a person pointed out to me:

Look at Twilight's rear, and then front of her torso. both are at different perspectives so it looks like her body is curved or zig-zaging. Also, I am missing the cutie mark (although I could say its being hidden that would make the her pose look even more wrong.)
