Very nice job on the proportions and posing, his muzzle looks a bit long though, but that could just be the tiger speaking. I wouldn't think the jacket would reveal his muscles as much as it does though, Especially if it were leather, which seems like a natrual choice for him.. but it could be anything.. liquid latex for all I know.
I do not like taurs... :C I think they are entirely unfeasible on a fundimental level... but, artistically speaking, you did it justice here. I'm possitive you already know this, but you should check out Kacey's art if you want some other good examples.
WOW! I agree with Cornus, this is an amazing piece of art! If I were to see a live fauxtaur tomorow, I wouldn't be suprised if it looked exactly like that! Amazing detail and reality. Keep up the phenominal work!
