How do I remove or blur the background of this image? I want to keep the water trough and the straw but loose the mother sheep etc to at least some degree of bluriness. I know I should have done this on shoot but I was just practising, then I got this shot and thought it was a very cute expression. Also what can I do to improve it PS wise also? I only know the real basics of CS2 any help at all would be fantastic, thanks in advance!!!
