The Buster Project is coming down to the final details. My mentor pointed out some problems with "edge integrity", i.e. all the dog's edges had to be crisp. Also there was a problem with the background being too "busy and linear". Connecting some rocks to the dog and eliminating a second flower bed behind the dog gave Buster some additional depth.
Next session will require some muzzle work. Right now, he looks like he has a giant black hole in his head. The muzzle is next, then a coat of varnish to make everything shine. Overall, I think he's a handsome boy and I'm reluctant to give the work to his owner.
