Thanks The collar was an accident. I was trying to think of how his hair would fall over the collar of the coat.. and these really cool furry looking lines appeared as I flicked the paintbrush so I just ran with it. I hardly ever plan-out a painting really. I just let it go where my right-brain takes it!
That is why Acrylics suit me, I think. I can add things later or paint over things and unlike oils or watercolors, it is easier to change things later. Although oils, you can do that too.. but I am too impatient to wait for them to dry! Though that could be an advantage I guess if reworking something..
