I sent a message back to them asking exactly what they were looking for because I didn't understand part of their request. I had started on the rest of the sig, and was waiting to piece in the weapon later when I came on here to find that you had already done one.
It is stated in bold print on the first page to only PM one artist. If you choose to get it done by someone else, or if you want to check on the status it is courteous to message that artist and let them know beforehand. Just grrr.
