Thanks! I'm always really hesitant to go so cartoon-y, when I feel like people are expecting this level of realism out of me from the rest of my body of work, so I'm really happy that these sticker designs are getting such a positive feedback right now. It really means a lot.
Don't! I think cartoony styles rock! Personally I find cartoony styles often more appealing than realism. Everyone can eventually draw realistic when they have enough experience, but to break down anatomy into some sweet style, it's something very personal and I thinkit's also really creative, moreso than being able to render and paint hyper realistic images. My opinion, anyway
