I can tell that you have skills to draw something great, but this image lacks so much creativity. It seems like you learned how to draw a “stereotypical cartoon style” and drew the same ugly male face for every character. The style doesn’t look unique, nor pleasing to the eye. Mlp is cute and fans want to see cute art. It seems like you drew these characters just to say, hey look, I can draw a million characters; they won’t look good or anything but at least I can draw. The heads are also too skinny imo. Granny Smith on the other hand, looks pretty good (head could be less skinny though).
