I think it's certainly nice and clean - love the colors and the subtle textures you've worked in. I realize this was just for fun as well - so take all this with a grain of salt. I'd reconsider how you've done the navigation - love it's layout and overall design - but as it stands right now it's borderline mystery meat. Also i'd work in a space for some messaging or a call to action over the main picture - something transparent so you don't lose the quality of the picture. Realistically there isn't much of a message being conveyed (again i realize it's for fun and a template of sorts) but if you wanted to really convince a business to utilize this you'd want to take that into account.

Overall though - I really like what you've done.
