I happen to stumble across artist Iain S Byrne by accident. He and I follow each other on Twitter and he posted a link to his Facebook page where I discovered his amazing art. He is a digital artist that makes his work look like it is done with real oil paints. He sells his works of art on Etsy in the form of Christmas cards and prints. Here is his Etsy store.
Most of his work is of wild birds. He devotes great attention to detail as evidenced in the picture below of a swan he has done.
This man certainly has talent. He has told me that he will be posting more horse art so you will want to visit his Facebook page and see his latest creations posted there.
