I agree with a lot of what's already been said. My main concern is that the font for your name is hard to read. Definitely go with something with upper/lower casing.

Also, I know you want to keep it vague because you do a lot of "cute stuff", but I think, when I shuffle through the cards in my wallet, that it's going to be hard to remember what, specifically, Tea's cute stuff consists of without a) a more Tea-specific piece of art there or b) a listing of some of your skills. I mean, it's a business card - if you were a scientist you'd say "scientist!" and list your specific fields. I think as an artist you should do the same. Of course, I have lots of artsy friends but remembering who does the screen printing and who does the murals and who draws in what style can be a little hard to remember at all times. :)
