The sketches look really nice. The muscles on the body look nice, and the dog faces look great as well. Love the detail on the lips, the ears, and the nose. But, aside from it,
If you're looking for some athletic, impressive, and I guess aesthetic female models, I suggest you check out Alana Blanchard (an American professional surfer and model), Malia Jones (another American profession surfer and model), and Michelle Jenneke (a Russian hurdler and model.) If you want to check out more, just look up "athletic female models".
thanks! i suppose the reason i was just wondering if people knew of any specifics is i like to get as much resource of a few bodies i can so i can mentally stitch the pictures together into a 3d person rather than taking the abs from this-legs from that- approach. That method is easier but doesn't really help me visualize how all the parts really weave together as a working unit. michelle jenneke is really good- i need the girls that are brazen enough to populate image search with bikini shots or more (less?) :P
