1) learn particle effects
2) what in the world are those 3 balls
3) the head should stay a constant size unless you are doing perspective
Hope this helps... :)
Not to boast but, you should work on those effects, movements,etc.......... It looks unattractive for me. The head is resizing too much which is why it can distract many people with it. And why is the body vanishing anyways? That is all:D
