gahaha I think they both are awesome. Love Carl...seems like the perfect geeky type. Maybe you can give him a D&D dice as a lucky charm or something :p
one more thing for Daniel, I know the style is just so it fits with your older portraits, but I just cant stand the highlight on his baldspot. it looks too big to be a specular, but it's too harshly contrasted to just be an extra skintone, so...you should either put a blending shade in there somewhere, OR make it an obvious specular ( one of the WIP versions makes it look more like a specular), maybe by giving it that typical window shape that identifies speculars? anyway, you should be able to figure it out :p I'm just throwing out ideas.
and MAN, that sketch looks even MORE like dr Wily XD. I insist you give Daniel a Wily-ish eyebrow wiggling emote :p
