Hmm, I don't know. I think siggys that look sort of like scrapbook pages look pretty cute (like luvmytiger's siggy maybe?). I really like sky blues and earthy greens.. and the symbol of a pawprint colored like Earth--I don't know why! (A global paw!

) So any of those elements might be a place to start, but feel free to let your creative side take over.. lol!
