Well you're welcome. And believe me, there might just be more critiquels where that came from! But not just to you, because aside from makeing random pixelart that I think to my opinion that is almost not worth posting it's so bad, I like to help others out by pointing out their small or sometimes large flaws. My only worry is that some people might take it the wrong way. But aside from all that, have fun and keep pixeling! :)

Oh thanks for the critique! :D (just in case... I'm not good at english :D and i'm easy to misunderstand, if by any chance my words are a bit rude or anything i'm sorry, i don't mean anything)

I got this website as my inspiration http://www.yarrninja.com/pixeltutorial/chapter15.htm a street fighter animation. I really like the way they run specially sakura... I think it's fine the way it is without moving the head since it's a normal run with a set goal. so moving only the body slightly is fine (this is what I did), but i think a run that it feels like you are running for your life or running with all your might might be the right feeling for the run that you are suggesting... but i'll try to research for more and maybe i'll find what you really meant and make my animation more better! thank you for the critique!! really I'll look forward for more of your critiques in the future :D

Looks cool, but if I may point out one flaw: you've got the bouncy motion and the correct leg movement and everything, but when running people tend to sort of rotate slightly towards the left and right with their bodies, and heads. But overall despite that small mistake, this was a job well done. :)
