I have a question for the very nice successful Red Bubble-Anon if they're still around.

I've been thinking about a foray into selling my illustrations for a while now, but from what I've seen the most successful designs tend to be pun illustrations, drawings centered around a play on words, t-shirt fodder like that.

Picture related is a wip, but it's the kind of stuff I usually like to draw. Illustrations of cute or interesting characters posing or engaging in various scenarios. I don't know that if what I draw is very commercial though, or whether anybody would interested in owning items with my drawings on them. What do you personally think? Could I be successful drawing stylised stuff like this?
