I used the "Craquelure" filter to create the rough texture. At least, it's rough from a distance. If you zoom in, it looks a bit like tiger stripes though. A funny coincidence. (And also, if you see distortions when you zoom in close on my images, I'm sorry. It might be an ipernity bug but I've been too busy to investigate that.)

Shown smaller than the original completed size of 2850 X 4500.
