Thanks! I was looking at the 'Katana, Oda Nobunaga' image particularly. I am not sure whether I'll use it sheathed or unsheathed yet, but I would likely incorporate it into the logo for one of my product lines on RPGNow. If I end up using it, I will definitely find some space on the readme page for image attribution. my e-mail address is posted on my profile, if you want to send me your real name. I can send you an example of what I'd use it for too.
I've done maps for novels before, though normally my work ends up in RPG products. I definitely do commissions, so feel free to keep me in mind when the time comes! Also, some of the best cartographers on the web can be found at The Cartographer's Guild: [link]
