Claymation for the first time IS always tough...
You're following the great road to claymation, my friend. Aardman (not on Newgrounds, but did "Chicken Run" and "Wallace and Gromit"), KNOX, and I'm sure there are more out there, have probably started out just like you. Sometimes you have this image in your head that the clay will follow it, but it's easier to think about it, than doing it. I gave you a "7" for effort and "4" for submitting!!
