2 and 5 remind me too much of katamari. And I'd do something like 1,6 and 7 for the three friends. Variation is key here. There's nothing that strikes me as protagonist material though.
Thanks, for the feedback, one of my friends said almost the exact same thing! I'm working on making the friends into models now, and I'll probably concept some more for the main guy.
Creo should be that blank, numberless one in the middle. 1-4-7-9 all have good sidekick potential about them...
Is this their whole body, or just their faces?
Yeah, the middle one is my vote for Creo too, but I'll probably tweak things a little more first. And these are essentially their whole body, I don't have the skill/time/resources to animate these guys, so I don't want to suggest any part of them could be articulated.
And based on everyone's feedback, I've taken a first pass on making number 6 as friend in the game. Here's what he looks like (I'm probably going to make him squatter, and clean up the lines):
