You can expect to wait at least two days if it is a small commission, and at least a week if it is a large commission. I cannot put an exact timetable because I work in phases towards the final product, but I will send you drafts consistently and steadily until a final design is decided upon. You can use the art for personal or commercial reasons, as long as you attribute the art to me in the case of a commercial product. If you are dissatisfied with the final product, then I will refund you and reserve the drafts for myself, but I would prefer that we work through an issue you might have to get a desirable end result.
