I am more a fan of detailed models, but if a model is stylized enough I can enjoy a simple model. Distinctive artistic style goes a long way. Some of my favorite simple Paper Toy designers would be Shin Tanaka, Matt Hawkins, and Tougui. Designs that would look cool in 2-D as well is key here. My favorite designers of detailed models are uhu02, OneStar (sesanow), Onepiece (7200ss), Kyuri, Jan Rukr, and Julius Perdana.
