If we’re giving art suggestions, item one page one for how to improve with this kind of thing is practice drawing faces, because that is by far the worst and most distracting part of the image, followed by the hands (which can be hard to draw even for talented artists) and the proportions.

By the way, sorry if I hurt your feelings. I know it’s not fun being criticized, but I’m just trying to help.

You asked for an honest opinion. Here’s mine.
 
This is very bad. The story structure is non existent. These guys, I have no clue who they are or why I should care about them.
 
Now here’s how to improve. Keep drawing, look at reference pictures and try to make it look them. Keep trying to improve and take criticism. The ponies all act exaggerated, out of character, or just insane. And the art is sub par.
 
I don’t mean any insult, that’s just my opinion.
 
Now instead of getting mad, try to improve.
 
For humans go to a site called Pixelovely and start doing some figure construction sketches. For ponies, look up some tutorials and start drawing.

This is as bad as I think it is.
