I don't draw, but I do design wargame simulations which often requires "electronic rendering" of existing images, often for no better reason than to get around copywrite issues. Maps, counter design and counter images are usually what i do. Havent had much opportunity this past couple of years, but I could dig out some "modified images of ships and aircraft if people would like to see.
im a bit embarrassed to show this stuff. i dont consider it to be art as such, more technical application, but some of it might be interesting.
