Kuro Sticker Design

I thought about making some stickers to put on RedBubble. This is the style I'm thinking of using for them. What do you think? 

(I'll make some game characters, youtubers, and some other TV characters too. Eventually. If I do make stickers, I'll release a complete set at once.)

What set should I make first? 1)FNAF 2)Markiplier 3)Borderlands
