I think that's a fine looking double and dog.

Regarding shooting released birds, I never thought of it as "fair", but I never thought of anything related to hunting with any weapon as "fair". It's a legal activity. I do it from time to time. I also use trapped pigeons to train with. Sometimes I shoot them, sometimes a dog will rough them up or kill one. I can't argue that it is "fair" to the pigeons. Don't think it is. I still do it.
