I’m loving the earthy textures, fun colors, illustrations and hand-drawn looking font. There are two tiny tweaks that I would suggest to make this site really great: make the background repeat smoother and use an image replacement on the nav rollover (so they don’t temporarily disappear).

Also, they have a lot of good information on the subpages but it might help skimming to put some subheads in there or section it out better – since it’s so much.
