Oh wow! I really like this! As soon as I saw it I knew it was Ender, that's kind of bad XD Bu good that you got him down to where I could recognize him And I don't think your anatomy is that bad actually. It has a stylized feel to it that I love Great job!
I know, I've only been doing this for a year; although I'm curious, other than the neck of the one in the forest, what other proportion problems are there? (and not the floating one either, it's not really meant to be anatomically correct) I like to hear the problems, I see a lot of them when it's too late to change, but some things slip by me
only a year? Wow! And the hooves need work, on all of them. You should study the anatomy of the legs more, and how the joints work. another thing is the necks and legs are too thick or two skinny for the body or head of the horse. Overall, great job!!!
