Hmm... I'm not even sure what kind of information I'd need to include to start out with.
It's a pencil sketch that I've cleaned up. Subject is male, average-to-tall height, nice close-up of a gun he has pointed in your face.
I know to scan it in, correct the levels... and that's about as far as I got before I hit uncharted territory.
Anyone here who has experience or helpful advice would be welcome if they wished.
