I don't mind at all! System, as in computer system or were you referring more to the art program I used to make this?
If you were referring to art programs, I scanned a pencil drawing and painted over it in paint tool sai- then took it to photoshop cs3 for touchups and effect edits. If you meant computer system, um... I can't quite remember the specs! Oops.
I hope this was informative...!
