cute, colour suggestion, I think the fire-esque red-orange on the hair was effective in your earlier version, and also redder dark tones

also with the animation you posted, there is one particular frame that is 1 pixel too high and causes a sudden jerky motion, also in this edit suggestion of frame re-use, on the middle length leg frame, to better transition the strides, the fiery hair needs a bit of work but the walk looks pretty smooth arm and leg motion wise
an artifact of a certain zoom level produced this, (i reproduced what I saw) and while it is ultra cute, not too sure if the mouth opening is a bit too busy or not, but just posted it to see what you thought, it could work if the cuteness is what you are pushing.

*just noticed the eyebrow inconsistencies might wanna look into that too
