I see what Jennifer means. I can see an SP creating an impressionist painting based on direct observation or perhaps doing a collage or something like that. I think an SP artist would more like to do art because it involves working with their hands. So in that way, it's more related to sports than anything.
When I'm working on my art, I'm quite impatient working with my hands, I just want to get my ideas out. Personally, I hate painting, because there's too much detail work. My drawings are comic book like:
Galaxy
Radioactive Saltines (this is oil pastel)
Castle of Satan
Search & Rescue
Du Bist Was Du Isst
Blitzkrieg
