-copy and pasted reply from the previous comment:I price things based on how long they take to do. For "sketch commissions" I give myself a maximum of about two hours. That's it. This took just over one. I can go way, way more detailed with only a few hours of extra time.I try to make sketch commissions clean and simple. I'm really not putting a lot of effort into them. When I do this stage for a bigger piece, it serves mainly to get a solid base down for the image before I go further.
