It is art yes, but it's not great art simply because it is done on a computer. I am not trying to say that it is not good, simply that since it does not exist in the physical world on a solid object it is not 'great'. When I see the end result, I just see a picture. There is nothing. There is no evidence of emotion in the brush stroke or feeling in the texture. His picture is just a bunch of pixels. It looks good but that is it.
