Look out for the Western anthology from Accent UK, hitting the shelf’s 2009. After I got picket up by Accent UK, they asked me if I would do a pin-up for the anthology. And of course I would.
The pin-up in western will be in black and white grey-tones. But I was realy happy with how the colors turned out, so here is a chance to see a breakdown of the process doing the pin-up, and the color-version of the finished artwork.

Sketch:

After doing some thumbnails, I came up with this sketch.
Linework:

Linework with brush and ecoline
Colors:

After scanning the linework as 1200dpi bitmap, it was converted into greyscale linework. And then colored in Photoshop.
