Hm. I love this. I reaallllyyy do. But..I think few things can be different?
--> Instead of having just plain ol' straight edges at the top of the blog/sidebar..add some brushes to soften it a bit.
--> I really dislike that font.

It is probably just me..but..my friend tends to use so many massively chunky fonts that it just makes me want to slit my wrists when I see fonts like that. Stupid, I know. I take things wayyy too seriously.
--> I agree with Carrie about the pattern thing. Have you tried any of the ones
here? There are 303 in the post, alone!

That's a lot of patterns.
--> Oh..back to the top of the bar things..I think it could be lowered just a tad. And with brushes over the top it'll look great.
I'm sorry I just think it needs a few tweeks. BUT I LOVE IT. Really. I do.
