Hi again,
From the video, if that is you, it looks like you do mostly drawings or paintings of people. However, if you do landscapes or abstract art, I was just saying that you could use them as desktop wallpaper. As far as the web site theme goes, people sometimes use art work or landscapes in the header of a web site template.
Now about your nickname "slasher". You have to ask yourself if someone looking for art is going to type the word "slasher" into the search engine. You also have to ask how many people know you by that name. You will probably need a name like "professional-artwork.com" or "art-pro.com". These are just examples. I don't know if they will work for you or not. You want to try to use words that you can also build your content around.
Here are a few other ideas to help you in the thought process.
people-art.com
abstract-art.com
amazing-artwork.com
art-for-sale.com
animal-art.com
I hope I didn't give too much information.
