I've taken a quick look at all 5 sites. Firstly, they're all exactly the same style. If you were subbing to me and I think to most LL's you'd have to wait a month between each site! Also the style is very minimalist, not a lot of interest or personality. I'd list them as they are but they could be given a bit more zest IMHO.
Google is a waste of an exit link - no money to be made there! Try a non-adult sponsor site like Warning Pages or Prank Place.
Your gallery pages only have 2 sponsor ads - might as well use the 3 you're allowed!
Don't be disheartened. You're very much on the right lines Just a bit of tweaking and you'll have some very good sites.
