Hey DankLord, thank you very much! Glad you enjoyed your adventure with Quidget! 
As for your question: One reason certainly is that it just went well with Beatrize's character, especially on her ingame character sprite (and I kinda wanted the busts to match that style).
That said, Peninja - The Funky Sexy Love Ninja RPG (the game we're currently developing and that Quidget is a spinoff of) will feature all kinds of women and men with different body types (because, well... I enjoy drawing different things ;) ).
Hope I could answer your question somehow!
