I tried, my horse anatomy isn't the best! ^^;
I find it easier to make black lines instead of red, so I just swaped the colors! cx
I could only blackline the profile sketch, I just couldn't do the front view one. and I'd skip the legs too cuz' one; I can't draw horse legs and two; I think your legs are good enough! c: your hooves are also great so I didn't have to line 'em.
hope it helps! c: <3
