It is well organized, I would however emphasize the name of your company more.
-Add a top header bar above your image at your default page with your companies name on it.
-You have a great idea for your image on the home page, however the picture clarity is poor (no offense). Find a better example, or maybe a before and after that is REALLY good clarity for your image.
-Also, fill in the tab bar to fit with the image, or don't leave that white border around the image and menue bars. It takes away from things a bit.
-Add a subscribe or news feed thread, maybe a facebook like option (don't need one, but happy customers may use it and it brings in more clientel).
-IMHO: Design a logo, or have a custom font for the "OKC" that pops the image more than just the default font that matches the same font as your website layout.
-Add a testimonials section
-The did you know section on the right-hand side of your page is good, but it's clustering with your description on the left-hand text fields. It's hard to make out, add a box or something around it.
Those are just a few of my opinions, I think more than anything... your site is good, but section things up a bit on the home page, and logo would really help. :xyxthumbs:
