For one thing, after being a member for ages, I finally uploaded a few convention sketches onto my Comicartfans account today.
If you don't know it, comicartfans is a great site, basically a repository for art collectors to upload, share and compare their original art and commissions. It's a fully searchable database of thousands of images, convention sketches, published and unpublished comic art and art commissions.
Apparently there are 223 pieces on there with my name on them, mostly lettering and titles. The most recent is a very nice Trevor VonEeden cover commissioned for Aidan Lacy's "Re-Legion" series
At the risk of stating the obvious, if you're a fan of comic art, you should join comicartfans.com.
