Oh hey, I miss this guy, hadn't seen him in a while.
My suggestion on the legs would be to either move the left leg out at the hip more (so the legs are more spread and the foot/knee are more facing the viewer) OR unbend the left knee some so the leg is more extended (it is perhaps a bit pinched).
But more importantly, I love this character~

Yeah, I've actually been meaning to try to draw him more lately, since I've been in a mood to.
I had a lot of issues with that one leg...the angle has been confusing me how to draw correctly, and I'm still not sure how to draw it facing outwards more. Trying to extend it might be less trouble though, I'm not sure. You're definitely right though...just not sure currently how to actually draw it correctly.

Definitely a challenging pose, but it's awesome to see this guy again! Now, are the legs to be on two different levels? If so, I'd suggest making a couple of small horizontal lines under the feet, if not entire steps, if it's to give the impression of them being on two different levels. Perhaps that may help the angles and depth?

Nah, the feet are actually supposed to be on the same level, just one is meant to be closer to the viewer. I probably didn't make that work right at all though. >_>

I see. I think what made me think that is the angle of his hips. They appear to be rotated to the right, further than his shoulders. Perhaps pulling his right cheek out slightly could provide itself as a better starting line.

Hmm, I think I see what you mean. Can try to fix that when I edit it.
