That's tough.
The plus is, being an artist you won't have an issue with content.
The minus is what level your coding skills are at.
If you have reasonable skills than I like a clean template like Chapelco where I can customize to my hearts delight.
If your skills aren't significant than your better off choosing a template that has the look that you would be happy with to backdrop your content.
This is all the template is, a backdrop for the content. It is the extensions such as RokGallery and RokSprocket that control the display of the content and they are easily integrated into any of our Joomla 2.5 and 3.0 templates.
In fact some of the template have these extension's already integrated into the template to showcase our demo content.
