Another piece of aviation art. This one took a lot longer than anticipated (3 weeks in total) as I had to design a new Photoshop brush to get the right effect on the painting of the camouflage.
The aircraft has been modified from the original photo shown in the comments to represent a Catalina Mk IVB JX286 of No. 205 Squadron RAF watching over a convoy on route to Great Britain in WW2. In the end I am quite pleased with it.
