Ok here's some things I noticed:
- Try to keep your image sizes below 100kB
- You use the same template for all the sites - changing colours is not a new template in a link list owners eyes - change the layout of all your pages, pics sizes and ads to make it look fresh. Link list owners recommend 30 templates so do a new one for 30 days and cycle through them after that!
- I would add more text with keywords for future SE traffic
There's probably more but that was what I noticed - feel free to add my link list to your submission list - you obviously know what you're doing!
