This is a 11 x 14 Acrylic Painting on hard board. Hard board, clayboard is used so i can put in the very fine details. if you look close you can see each feather's barb and after feathers. This is an European Robin some times called an English Robin, a little different from the one found in the US . It is winter season and they get a little more puffy . We had Prairie Chickens this year freeze to death just sitting on the branches of the trees, very sad.
