The site feels busy. I would suggest removing the heads of the 2 boys from the bottom of each content area.
The navigation font is terrible. You should not be using font images as your navigation. Its makes it really hard for search engines to correctly index your web site.
Coding in tables is also another big problem. Tables are out dated and honestly a terrible way to develop a web site.
Design wise there is not much happening. I'm assuming that box thing on the homepage is supposed to look like a box that you would by software in. The perspective on that box is off.

See how on that photo the box has a clearly defined edge and side. The sides point towards the center of the box.
Those orange things on the box look alright but I would try adding a strong gradient onto them.
On the left is how it currently look and the right is how I could change it.
