Ah, no. I can see where you're coming from with this. 
I'm semi new to pixeling and have been trying to figure out things like limited pallettes and stuff that work/don't work for each piece. 

Deviant art members seem to like to add white outlines to their icons... to make them "pop" i suppose. 

But for here, I'll make sure to pick and choose, or altogether learn how to work the white outline out completely from all of my pieces.

ah, yeah. Was on a white background before. x'D So It blended out nicer with that colour. Didn't realise how funny it'd look with another colour background. I'll remember to change things before posting,

@James:: *Stares at* ... I... Think you're right. Thanks.

YES! I've played both games and this made me laugh so hard. X'D

You got the details on the three Collosi verry well. :o [Love how you added the guy's outfit to the katamari.]

Especialy for only unsing references. [Playing the game helps since you have to climb around the entire beast. You get to know 'em pretty well. X'D]
