Your anatomy skills make mine feel inadequate and shriveled

I mean that in a complimentary manner

Also diggin' the variation in the line weight -- might I recommend thickening the lines where two lines meet at an angle, and filling in the acute side of the angle, if that makes sense? I think that's the effect you're going for and I do it too and I love it c:

If the whole piece comes out as nice as the sketch I've seen does, then your rate of improvement continues to be astronomical xD

This is actually the first bit of art I've seen from you in a while (mostly cause I haven't been on FA, like you :x ), and I have to say you've improved, sir :D The expression and the lines are really sharp, nice job broski. Keep it up :3
