The 1st and 4th frames last for 150ms and the others 100ms. It creates a cool timing for the arms maybe, but the hair and scarf's movement look weird because of it.
The hair is kind of expanding. Not so much in the latest version, but keep in mind keeping its overall size consistent.

The thing that bothers me the most is that the body falls instead of rising in the frames the legs extend. It's like that when walking because there's always a foot in the ground, but running is like making small leaps I guess



I quickly fixed those things. All frames 100ms long.
I also tried to separate the front leg from the back leg a bit, cleaned some things a bit, and made a less cazy scarf animation.

I hope it helps in any way or gives you ideas.

Well it's hard to edit because I don't know what the object is, but I cleaned it a bit.


Didn't change the colors (Edit: I actually changed the yellow so it had some more contrast with the darker one), but I added a third yellow color for the middle part for separating each yellow stripe (it looks like crap but I'll leave it like that) because I'm not a fan of "outlines" inside the sprite.
The part where the yellow arrow is pointing to looked weird because there were more outline than actual object (I don't mean it can't work, but in this case I think you can make it a bit bigger so it looks better).
I changed the single pixels in the handle to simple shapes so it doesn't look so noisy and added a bit of autoaliasing to some other parts but I didn't put a lot of thought to it

I'd like to know what it's supposed to be. I guess I don't know it because I would recognise it, but I'm curious about it.

Looks pretty fun. It reminds me a lot to Toby Dixon's style, but I guess are aware : )

Use the link with the .png or .gif at the end and put it between [img ] and [/img ] (without the spaces) and post it at original size. If you click any image in the forum it will zoom in

I like this kind of stuff, and it looks ok, but they could be a lot more interesting.
I would change the timing of the movements and make movements faster or slower, maybe adding some ease-in or ease-out too.
The sprites themselves look kind of plain because of the colors. There isn't a lot of contrast and grey isn't the most interesting color

You usually save it as .gif and upload it to imgur, unless it's a linear long animation or something instead of a loop.
