I thought I might have another go at animating.

I can't use the brush tool btw.

Whatcha think?

The explosion could've used more particles, but it's ok.
The walk was quite stiff, and it didn't loop very well.

Make the arms two parts, upper and lower, animate them individually. You don't walk with your arms perfectly stiff, do you? Same with the legs. The loop also doesn't flow well there's a chop at the end. Your explosion, although generic, is okay looking. Except for the flashing on and off that's just unnecessary. Try to draw bigger to fit the screen also.

Thanks for the input guys.

Do you think I should animate each individual part instead of the whole stick at one time?
