So far I've purchased three pices of art work from artists here on deviantart, two for dnd characters, and one since I liked the concept.
The first was a drow warrior, he is a follower of the god Talos (forgotten realms) and used a quite unique weapon. The picture cost at the time 80$, but then I got a print, and a large sized file on a CD so I could print more should I need to.
The second was from the same artist, this time a female drider, the idea for the armor I got from another picture I saw somewhere here on the site, and it turned out really good, this cost 90$ still with print and CD with the large file.
Lately another talented artist held a burst commision at 40$, witch was quite a deal since it was normally 100$, altough there was a few restrictions on the level of detail, the final picture was very pretty, with his commision I got a file to download, aswell as the wallpaper version you can see in the favorties.
