That's a nice banner, but no logo, if that's what you are saying you changed is the logo. I think that images works well for a banner. But Where you have your text at the top left, "Simply Freeware", you could have a logo right next to that. Since I'm not working on my template at the moment (Cuz no one has commented!) I'll go ahead and have a shot at creating a logo for your site so maybe you can get an idea of a logo? (If you don't mind that is)
