Interesting grid structure with a cartoon illustration design. The header is longer than it should be, but the design concept is very well done aside from this issue.
Cartoon style background and effective color scheme that does not distract from the main purpose of the site. However, the header should be shortened to bring the "Welcome" information within the screen's view without scrolling.
The image banner could be structured better, but the grid layout of such a content heavy page works very well and gives the illusion of line throughout.
Similarity is used throughout the navigation and header, as well as with the grid layout and continuation of the text effects in the main content. The texts visual hierarchy could be structured better, however.
