Don't lie, that's really good.
Only thing I'm against is the 1st and the 5th frame with the idle pose.
Those frames don't fit in with the walk and the animation actually looks better if you either delete those two frames
or redraw them so that one foot is moving forward in the air but close to the ground.
I hope you plan to draw more creatures. I like the colors you selected.
The shadows and the highlights are quite effective. The dust is a nice touch.
Have you got an idea for a game?
