They're all working for me, haven't seen a problem since you started the thread.
I made a quick edit yesterday, I know it's a big style jump but there's just a few points I'd like to highlight.
Firstly the leg positioning just doesn't look natural to me, I mean im sure you could pose like this but being realistic who does? Legs just seem a tad too wide spread in my opinion. And his hands just seem to be up just because, that's just where you've decided to put them. If I was doing this it'd feel much more natural to have my fists up to protect my head. Be grounded but be stood comfortable enough to move.
Well here's my edit, While doing this I thought to myself 'hey, he kinda looks like spock from Star trek, so yeah here's spock to illustrate.'
Bit of a palette edit too, thought it needed some added variation. Also som more clothing folds, skin tight doesn't seem right
