Small pieces such as sketches take 1-2 days and are at a fixed price. Large and detailed pieces take 1-3 weeks, and are priced by $/hr worked, with a given estimate on work time. Current rate is $10/hr, working +50hrs for fully rendered pieces. I'll let you know when I start, and if any issues/delays come up. If you have any problems with the drawing, let me know and I'll make any needed adjustments (includes progress snaps so you can make sure you're getting what you want).
