Cute, but I think there could've been better options in putting the 3 boxed images at the side.

Classy.

Nice images, but I think it looks rather disorganised. And I'm not keen on the idea of having two patterned sections..

Perhaps making the other colours out of the rainbow less severe, like using light pastal shades instead, would make the rainbow fit in more. It wouldn't hurt to make the rainbow more "blended" too.

I like the brushes, but I think the colours didn't match each other very well.

The past 3 commenters didn't like the skin. I, on the contrary, think it's very well-done.

You CAN make changes to the scrollbar, even if you're using Firefox. It's just that you can't see them.

It feels really "empty" at the left. Having just one brush pattern type over it doesn't help very much.

You have a great picture but not a very good layout. I think you should not have given it a border. The double lines beside it were unnecessary too. Perhaps you could make the image smaller, as wide contents are not very nice.

Image quality not very good, and same goes for the choice of font.
