Idea #1 - Do what you think is best. I trust your vision and ability as an artist :)
Idea #2 - use a distinctive art style. Em likes:
- Art Deco (http://99designs.com/designer-blog/…ic-design/)
- Art Nouveau (http://99designs.com/designer-blog/…spiration/)
- De Stijl (http://99designs.com/designer-blog/…-movement/)
- Bauhaus (http://blog.visual.ly/six-lessons-f…e-graphic/)
- Surrealism (http://pinterest.com/garyself1949/a…urrealism/)
- Japanese wood block (http://pinterest.com/masjoden/japan…ck-prints/)
Idea #3 - illustrate Townes in the style of one of Em's favourite historical or fictional characters.
- Sherlock Holmes
- A Spanish Anarchist
- Dr Who (David Tennant, Tom Baker or Peter Davison)
- Townes Van Zandt (This is who Townes is named after, maybe you could illustrate a Townes Van Zandt album cover with Townes the cat taking the place of Townes the musician!)
If you decide to go with illustrating Townes in the image of a character, please be sure to make it look as much like Townes as possible, and not just any old cat. You don't need to go all-out with fancy dress - just a few things to make the cat identifiable as the character.
If you're going with a particular art style, it will definitely help if the cat looks distinctly like Townes, though there is more room to move here. Getting the style right is the more important thing to focus on. Something abstract might work well, though I don't have any ideas about how it would be done.
If you have a great idea and I've not mentioned it, check with me! Em likes many other things that I have not listed here.
As aforementioned, use of these ideas is NOT necessary - if you're a great artist and can illustrate a great cat without gimmicks then go for it :)
