yah i can notice it. but for somebody that doesn't use it i would say it's better than others i've seen that don't use it. anatomy can be fun to study though. definetly worth it to look into it. and i would agree with rovanna that they do look balanced.
The proportions are fine, they are cartoony, but look balanced.
You may not like my answer, but I suggest learning life drawing, and drawing real people from ferences. That's how all pro anime artists and cartoonists learn about the human body. It will help you to see the human body as a 3D form and will make your poses look more natural.
Naw~ your answer is fine, and I asked for it If I couldn't handle some constructive criticism it would be dumb to expose myself to it~ I suppose you're right, and I'll give it a try. I usually draw off my knowledge of the body(head, neck, shoulders, so on and so forth), and usually make the pose as I go along. Thanks again for your opinion~
