Thanks vegaskip, I have the disruptive pattern available but the commissioner is really happy with the result having okayed black and white to start with. So no problem but I really appreciate the offer. I have however, added a touch of color though in the sea and the flag and a tiny bit of blue in the corsairs. This is entirely colored pencil (mainly Polychromos) and took approx 20 hours. Its on Bockingham B.21 180gsm paper A3 size.
This is the finished article, scanned at 400 dpi then resampled down to 700 x 495 for the web.
Not much aviation in the pic I accept but hey..
