Review my site Artevolve - Remix and Derive Artwork/Photographs
ow: I think that your design would be much more successful if it were more visually content-centric. Focus on 1-3 of the best images (I guess based on your voting system) to show off on the front page. "Finally a Home 
for your Creative Work!" is too generic. It forces me to read each paragraph below to know what's going on. Try explaining the site in a few bullet points reinforced with descriptive and visually appealing icons. If you try that stuff out I think it would also positively influence the flow of the rest of the site.
