I suppose it depends on what image you're trying to project. The main photo of you doesn't show any emotion, and neither do some of the others, so I think I'd choose pics that conveyed whatever image you want people to have of you. You have a great smile, for example. You could use that to your advantage. Or you could look bored. Or scowl. Or flirt. Get the idea? It's just my own opinion, but I love pics that show emotion, both through the eyes as well as body language. The overall impression of the guy will make me want to join a solo model site, not just his dick.
