Basically what You have there is the start of a hub site, Your gallery pages should be removed and put on free sites instead, as stated a free site is a site with 1 warning page where the recips go, a main page and 2 or more gallery pages, I would say max 4 gallery pages (I never do more than 2 gallery pages myself)
Go check out some of the free sites listed on link lists and get some ideas from there.
Here is my own hub site:

I don't know if it is a good hub, but a hub it is or some would maybe call it a fake link list. I use it to list all the free sites I build, but I dont have recips on the sites listed at my hub, so if a surfer makes it to my hub, I won't "leak" traffic to other peoples link lists.
