As I said in an earlier post today I've been through A LOT of sites in the past couple of days. I like your site as it stands. I think it is very clean and professional yet polished. It would rank in my top 10. The only color I would change is the yellow/green one. I think the blues are fine. I think the yellow alternative you provided is too much...yellow. One of the first things I notice at a site is unique fonts. I really like yours! Hope this helps.

Make it a great day!
