I'm not saying it's easy to create, it takes a lot of talent and skill . . . I never feel fully in touch with my computer art. It's a disembodied tool with preset functions that you customize and make your own. But it's not a painting. I see a lot of wonderful digital art there.
People are much more impressed with the paintings than the digital art.
There is one simple explanation for this. Most people have seen a much larger amount of traditional art than digital in their lifetime. One person who is perhaps the most qualified to critique digital art is Charles Csuri. Csuri is an artist and a true pioneer of digital art. In 1967, he was awarded the prize for animation at the 4th International Experimental Film Festival in Belgium.
