You're really keeping yourself busy with those, aren't you.
There are some small errors in mane (I'm guessing you're still using Photoshop then) and her back leg (the line connecting body and leg is wobbly, forgot the name because I'm a derp), same with front left. You also seem to have forgotten eyelashes on her left eye. The shadow could be a bit darker too, it's barely distinguishable.
You're steadily getting better, good job and keep having fun.
Sorry for always being the guy who comes in to criticize you, but that's the best way to learn. No hard feelings. <3
Yeah, I tried Illustrator but I did not like layer system thing. Also I figured the eyelashes were behind the mane. And I think I'm using a bad colour guide, I have noticed ( you did mean the back legs and not on the ground didn't you...)
It is fun, but lectures restart tomorrow, so my priorities will have to change... Thank You.
