Detail work time! I also went ahead and reintroduced the background and foreground elements. Not much to say about these steps. The eyes, nails and fighting claws were a mix of my previously mentioned techniques.
I like to be very fluid as I work in painter, and I would encourage the same of anyone picking the program up. For the background/foreground I moved through several different brush and style types, just building color and then shapes on a black background.
Make sure to use plenty of references when you work on anything, in this case I bounced between images of volcanoes, ash fall, and even a few images form the 2007 San Diego fires. I also slapped a few layer into the piece to get the background to look more hazy, getting it to look a bit further off in the heat and haze.
I feel that it has come close to finished so I am gonna shift a bit here and looking at our character.
