You're having a decent start, but you are definitely suffering from some layout and graphic issues. I am not trying to be a dick, just honest about the feedback to help you out.
1) I thnk your Featured Listings section need serious improvement to make you look more professional.
2) Latest listing modules need improvement
3) You have 3 separate modules on the bottom, all hosting links. Your SEO would benefit from giving them at least an H3 TITLE. and you can use module variations to give them 'flavor'
4) Popular listings can be improved with a few tweaks so it looks and flows better
The map is great.
Good luck!
