Looking Modern, but not to put a bucket of water on your flames of excitement Kip, your site has some validation errors buddy.
The home page = 7 errors, 1 warning.
Prices Page = 134 errors, 2 warnings.
About Page = 7 errors, 0 warnings.
Services Page = 12 errors, 0 warnings.
I will not put any more here as i feel like i am being cruel, to check your script's validation quality to the W3C Standards level use this link below buddy!
W3C HTML Compliancy Checker.All minor amendments to the script buddy will fix these and allow you to also promote that your site is then W3C Compliant.
But as a couple of people have mentioned the paint graphic worked well and the pure white back was fresh and worked well IMO.
How about using what you have but putting a hint of the paint lines across the top right or left corner at an angle of 45 degree's ish.
If you wish to fit more content within the same area use tab sections for this, see a good tutorial here:
3 state CSS TabsI hope this helps,
as always, if you need a helping hand just shout.
