http://www.robarspages.ca/aphc/index.asp please have a look at a mock-up for a new project i'm working on. What changes would you all make? (keep in mind that the client wanted the site's colors to match those of his logo. Nothing I could do about those colors. )
Nice colors and layout. As for the boxes to the right add come light green or gray background. As for matching the logo colors you could use the color theory picking one of the color harmony approaches. For Triad method it could be #3C2754 or # 684E30, complimenting color would be #662F35, or even you could use the hexad method.
It looks good to me,but you can improve it with Kassi suggestion.Only thing you might consider is the size of all your images (the big one have 231.71KB).
