Real nice imagination. I really like your style although is sometimes too heaavy spaced. your effects are really cool as well. Your problem is stiffness, try to move every joint so that it makes it non stiff and that it makes sence. Make sure one frame makes perfect simphony with the other so that you have a fluent/smooth animation. That`s all I can say and hope you get intermediate soon.
From my point of view you are high beginner.
