Time and time again, I receive reference sheets that are difficult to read in some way or another. They're either screencaptures from SecondLife, shaded with unclear swatches, or just plain inconsistent. I tend to spend a lot more time on pieces like these, when I have to spend an unusually long time reading a reference sheet.
The question is, would it be fair of me to implement a "difficult reference sheet" charge to make up for the additional time spent on the piece? Clients, would this deter you from commissioning an artist, if they had that kind of fee?
I know there's fees out there for complicated characters, but this is slightly different. I've had characters that ended up being relatively simple, but still spend forever interpreting the reference sheet before seeing their simplicity.
Thanks to any thoughts regarding this topic!
