Yes I agree, ask one of the mods for extra space. Your drawing is looking great so far! I would suggest you:

-smooth out some of the rough edges around the entire outline of the horse
-add a bit of detail to the eye, and maybe some on the mouth
-give her some more mane hair
-and make the background not quite as blurry
