the back/right leg (our right) does not seem to be making the same motion as the others, while it walks. Almost like it's limping.. You need to make sure you have it at this angle, in one frame ---> /
right now it only appears at this angle --> \ all the time, while the others go through both angles, creating the illusion that it's actually preforming a walk. Looking much better though now, great improvement.
edit: i really hope that made sense, i am on my laptop, and i haven't a gif editor to do an edit. also, finish davey jones! the lineart is really good.
