of course! i'm not great at explaining things virtually so please forgive me, i'm going to try to be as constructive as possible but i've never done this before <3

i really like the shape of the body and how you drew the limbs, your style is quite evident and i think it's important that it's unique! the back back hoof is a teensy bit big, i'd suggest making it slightly smaller than the one in the front of it (if that makes sense?) to show some depth. i love how you made sure to add the withers (bump at the end of the horse's neck) as well as the dip in the horse's back, since those are often overlooked. back legs are quite difficult at first, how i learned the basic shape was by looking at horse references and just kind of studying them. i made an old sketch a while ago (which is outdated from my current style) that sort of shows the basics of where things bend, you can find it here. i would suggest making the back a bit longer (roughly 3 or 4 heads long if i remember correctly) although you go with what you think works with your style! i think that this is an awesome fullbody, and, like i said earlier, your art style is super cute! i hope none of this came off in a mean way, that wasn't my intent. feel free to browse my drawings and reference off of them if you'd like, i really don't mind. i hope that this helped! <3
