For the Avalanche blog (not by choice, I assure you).
I had a rough version of this that I thought was probably finished but then some extra time led me to push it more. I'm glad. A little trick you may want to try with your next digital painting. run the blur filter when you think it is getting close to finished, then sharpen the selected areas that need it. This is similar to the method that I use with figure drawing. Build it up, then mash it all down, then build again, repeat as needed.
