Probably since it's from my early Carrara days and thus way back in the depths of my gallery. Few people visit that, and few ever did. Some of my first tests with 3D - like the dragon "cookout" and some renders for a forum game (Food Fiiiiiight!!! <--- Thread name) were from back then. A cat throwing pies at a dragon, and two dragons putting a dog in a catapult (Dogs are food to dragons bud. They're tossing him at rival dragons I wager.) That one in particular was done in response to another "dragon" on the forum who started tossing cats at me as her dragon 'avatar'.
Anyway. For one reason or another they hardly get any attention, and few people ever venture past the first page or so of my gallery, even on FA, so that's pretty much the reason why you haven't seen it.
