You guys may have heard about this before, but incase you haven't:
Isaac Yue (Red Bean) and Kaminoan have started a new LEGO website dedicated to Minifig Customization. The site has its own forum, but what really makes it special are all of the extra features. The site has sticker templates, exhibition of some of the best minifig customizations around, a look at LEGO and Non LEGO (MegaBloks, BestLock, Oxford) fig accessories, and much more.
Two CC members are active over there: Ramus and Recluce Mage - and they are eager and happy to answer any of your customization questions.
