Having posted a scan of the pencilled robin I thought I'd try colouring it on Photoshop. I struggle with Photoshop as a colouring tool mainly because I don't yet have the skills or knowledge to make it do what I want. For me, at the moment, Photoshop is like watercolour, working more with lucky accidents than anything else. Anyway here's the picture and I'm quite pleased with how it's turned out. I'm hoping to watercolour the original later today and post it in the morning.
