Here's a nice list to start out with

About the recips: most LL's accept anything from 6-20 recips, but with 20 it can start looking a bit messy when using the standard recips, custom text recips are better then.
About your site:
You aren't going to get listed using only 3 recips.
I would advice you to read the rules of each LL before you start submitting... You are breaking several rules of Link-o-rama for instance.
#1 You are using only 3 recips while the rules state you have to have at least 5 recips to other LL's.
#2 At least 20 pics per site, 10 per page. You only have 16 pics on your site
Other than that your site looks decent
