I'm going to chime in as a fellow artist. Obviously not as good as the others. But something does feel off in the drawing. It's something that has been bugging me since the first sketch. It's either the arm, perspective or the kneeling+twisting pose that sets something off with the entire pose. I always get the impression that his arm is too long. But otherwise it looks awesome and love the eye for detail. I honestly would leave the eyes out. It's a statue after all. And some wrinkles couldn't hurt.

And hush, we don't talk about a certain large collection of other drawings on this board lol. Even though they're awesome.
