Close! I did some minor tweaks here, the overall motions are good but the arm needed a slight bit of tweaking (notably, I removed a pixel on the shoulder to imply rotation) and I extended the back leg out more on the forward-swing so it better matched the foreground leg!
(I also resized it to original resolution, pixelation has a script in play that allows you to click on images to resize them without loss in quality, posting at original resolution makes it easier to do tweaks like this for illustrative purposes!)
