I remember doing stuff like this before working on flash. There's some good movement in this video; good job :)

welcome to the world of stop motion my man, nice start. If you need any tips or advice hit me up.

Interesting.

Not bad. The movement is nice and smooth. It's good for a start.

I think this looks very nice, it's simple but definitely better than anything I'd create with clay ;D
I like the colour you've used for the material and the subtle movements on the character, makes it feel slightly more alive.

I'd obviously add more things to add like sounds, music, more length etc. but as you make more animations like these you'll be learning those things on the way. Keep up! ^_^
