(eg. red vs green = no go).

Heh, true - but if you wish something to stand out, they are complimentary and are the best thing to show contrast =]

And.. this is practically advertising. Most of us havent seen your old one - why not post a screenshot? And the text here is copied from the website itself..

Anyway, critique. To me it seems like a website of mixed styles, and certain things dont work. First off, its very.. windows 98. I dont know what it is, but usually a plain website looks good - this just looks plain, and old. Maybe once again changing the colors round might work - a lighter scheme perhaps? Maybe changing the gray for one of the greens in the banner might look good, I dont know, but blue and green are analogous colors, so should work together well here.

Uhrrm, the flash buttons are okay, the bevel is huge. Nice rollover effect.. hrm, as soon as the page loaded, I looked straight at the "GFX Grotto" affiliate button. Its ugly as fuck, I'd either remove it (which you dont want to do) or move the affiliates section, further off the page - at the bottom perhaps?

Uhrrrm, ah yes. You dont need two navigations, have either the horizontal or vertical. Id suggest the horizontal - fits better. On the left you could fill in with recent news, or recent artwork - maybe a shoutbox or forums link or something =]

It probably seemed as if that was quite a harsh critique, but its in my nature - I'm sure the site has developed well, and It doesnt look too bad at all atm, just doesnt have that wow factor
