Screenshots look fine, but you're going to want a video at the very least in order to get even initial interest from a half-decent publisher, and you'd better have a demo ready to back it up too. I hope you've already had plenty of feedback from people who've never played the game before, because that demo is going to need to impress.
You're also going to want to post somewhere other than these forums to attract the vast majority of publishers.
