Interesting concept. It's weird, I first looked at the screenshots and was thinking it looked kinda janked, but then watching the organisms move around is super cool and unique. This game has a unique style to it and to build a full zoo tycoon in your own engine is pretty slick. Audio could've served well here if each of the animals had its own sound and some like visitor commotion in the background.  How many fire dudes do you have in that pen on your cover art to have all those patrons that happy?
