oh man, that's a gorgeous job you've done. if you're worried about harsh lines, you can always soften it in the computer or go over it with a white/light (pastel, pencil, ink) but it's really good and my favorite sort of dog. (despite the mutts i've had and adored) really excellent observation and an appealing gestural quality.
This one is quite a challenge. I like to add a lot of detail to the portrait but I'm not doing well achieving a nice soft texture to the longer fur. =/
This is the first time I'm working with such a great photograph... that I'm very doubtful I can do it justice. Trying to make a work of art out of a work of art! LOL
