It's ammeature, photos and design.
A lot of the photos look like they've been taken on a cheap compact, or a budget SLR with budget-end glass.
The lighting, half of them look like they were taken with naked flash or on-board flash... a bit of diffusion and actually making the white background white would have made the lack of image quality not so apparent, at least to my picky eyes!
and thats exactly why the black horribleness is there around the photos... they couldn't be bothered to make the images all uniformly white on the background (which is the whole point of a white background, to be honest) and just made it black so it didn't look weird, and to me, this hasnt worked, it just looks poor, a rush job at this point.
the rest of the site however is really good and effective... without the black uglyness in the middle and the black bar at the top which really annoys my eye, i'd give it a 4/5.
i'm SO glad i can do all this myself... and better.
and it'd actually work too, look at the link section at the bottom left, only 'products' work, the rest do not. The ones in the top right work just fine, how the hell can anyone over look that?! they've tried to link to HTML pages instead of the PHP's that actually exist... wowza. I can't beleive the site has been allowed to go live!
screw doing architecture, i'll go off to do web design instead...
Edit : the bottom left works when viewing a guitar in the products section, those are correctly linked up. The rest however are not, what a thorough little design company...
