Right-brain/left-brain quiz for artists

I'm sure it's a great oversimplication but I found this online quiz that is supposed to tell you whether you are predominantly using your right-brain or your left-brain.

I came out as 80% right-brain but I think that is probably quite a lot higher than it would have been if there hadn't been a number of questions where I wanted the sometimes/sometimes option instead of yes/no or maybe just an 'it depends' option!!!
