How does it look?

So now that the site has been up for a good 2-3 weeks, I'd like some feedback on it. Just general things really, I don't plan to change a lot of it, but I would like to know what people think.

1. How are the colours? Is anything too bright, or too dull?
2. How is the font sizes? Is everything easy to read?
3. How is the spacing? Is everything clear and spread out enough?

The header and the background colours are pretty much the only thing I want to change consistently, so I'd like to make sure these things don't mess up anything else. The headers I've already done (about 7 or so) and I'll match each header with an appropriate background colour. I'm really loving this pink though (the one at the moment) and it matches with the header which is a bonus.

I'll do a post when I decide to change the header/colours so you can hit refresh, in case your cache decides it doesn't want to recheck for changes.
