As of late I have been trying to churn out several tilesets.
My strong point is graphics, especially custom ones. I enjoy doing custom graphics for people, and I do take requests as long as it is something new and original, or an improvement to something that already exists. I don't rip a lot of things for people, as it doesn't test my skill, but I will do it on occasion.
Contact me via IRC to place a request. I can usually be found in the SMWC room between 8:00-11:00 pm eastern time.
