Hey great idea, and thanks for sharing this here dzero2. [righton]
The site is fine... but i have a couple simple requests/thoughts...
#1) please increase the size of the type in the bottom section, within those squares... it's currently illegible. And i suggest using a sans-serif font to help make it cleaner/easier to read too. Also... don't use ALL CAPS. It's hard to read and most folks don't care for that type of text formatting anyway. Besides... increasing the text size will serve the same purpose.
#2) I think that providing a sample graphic of what each brush looks like is a "nice gesture" for your visitors. I know myself that if i can't preview a resource like that i simple won't bother with it -- because it means i have to download/save/install/open PS/and load all those resources... just to find out i don't like them and won't use them. So to avoid this hassle/frustration for your visitors, load the brush yourself and using black, click the brush once in a medium sized canvas to create/save a sample of it as previews. People will appreciate this gesture very much and keep returning for more. And... they also won't hesitate to pass on your url next time someone asks if they know of any good PS resource sites.
