Hmm when I see your setup, I think it perfect for a terrestrial tarantula or a skink. Not a BTS but one of those Mabuya sp. Or any other ground dwelling lizard like you mentioned. And emerald swift would be neat too.
Oh wait, now that I notice your branches, I don't think a T would be good. Might fall and burst!
