It's certainly not bad for a first time I remember that my first walkcycle sucked bigtime

It does need quite some work though to make it look right:
I saw some popping at the knees.
The overall cycle gave me the impresion it was a big ogre instead of a happy sandman, it would also be fun if his eyes would do some secondary motion so that it looks like if he has to correct himself all the time I assume that his eyes are made up off those little boxes where you can shuffle this black circular thing with?
This will add believeability to the animation.


Remeber that it's not about how many walkcycles you have made it's about having fun and strive to make a quality walkcycle
