Just had another look (just to see whether I agreed/disagreed with the comments that I hadn't read before the first look).
I still like it. I like all the strong colours & I think they bind the pages together OK as they're the same tones & the pages are similar in style.
Never mind all the theory about web design. If you like your site then keep it that way. It'd be boring if all sites followed the same rules. Its a personal site, so its personal style. Very scrummy
