My Lego DC Army

Assuming my spreadsheet is up to date I have nearly 150 characters here. Keep in mind there are a few figures here that are my own purist customs that are still in progress (Parasite, Sergeant Rock, and Atomic Skull, most notably) and I need to find a head for my Larfleeze figure on the far right. Thoughts? Also yes, not all of these are official and I am aware. I don't mind getting these figures from other places as long as they look Lego-y enough. Who should I try to add to my collection...
