I like the new site, certainly pleased to find an RPG related social networking site. As an RPG cartographer this is an excellent resource and certainly provides a good location to supply a few bits and bobs to the roleplaying community.
First off, I've got some maps in my photo-album here that will act as a mini-portfolio. There is a free pack of higher resolution maps here:
Here's a sample battlemap from the set:
I also have a pack of free map-tiles that are created for use inside Virtual Tabletop Programs such as maptool:
Finally, many of my maps are available on the RPGNow store. These come in colour and black and white printable pdfs that allow you to print out your battlemaps for the tabletop, as well as high res jpgs for use in online play. Not bad for $1 a pop:
Oh, and of course the link to my website for a larger overall gallery of my work. Enjoy!
