Looks good. The face is, as previously said, not very defined, and his crotch is too big

??

Maybe darken the outline on the hair above the face? This is a lot better, though

Not to be rude, but it looks like he's "tea bagging." Also, that looks way to awkward for an idle stance if you'd ask me.

Has it been decided what his official moveset will be?

It makes no point spriting him if we haven't preplanned what exactly we are spriting.

What did we decide again? Sword or Axe? if it's a sword, that pose is fine I think. Doesn't look like he's tea-bagging really, he's just energetically prepared to strike/be striked.

If it's an axe, I don't think that pose would work all that well. It'd be much cooler (and make more sense for that matter) to have him just standing there, all relaxed with some massive axe over his shoulder.

Come on, you cant think that Isaac doesn't look cooler in that pose than fighters with lighter weapons. This pose is just to highlight his strength, and make him look more awesome
