So I posted these here AND on my RHG page because I rarely get critiques on my demos in that.
So I came here.

New demo 1
A bit too fast for my taste :/
New Demo 2
(Yes I know I forgot to get rid of the trails on the last frame)

work on your shakiness mostly, super shakey

your legs are superb

well... the animation is still rough also the movement need to following the arcs
Practice more, time by time it will geting better!
Keep it up!

Same thing as past animations, work on foot placement. :\

Yep.

in my opinion the one that you said is too fast looks better than the second one.

one way to solve the leg wobbliness, this is just my idea, duplicate a frame (should be F6) where hes leaning forwards or backwards and erase the body but leave the legs, then skew the legs to make it look more natural and then draw the rest of the body.

Really, your biggest weakness is definitely the whole "my lines wobble like mad" biz. I'd recommend you do some line exercises with your drawing tablet or something similar.

Check the first part. That should probably help a bit.

EDIT: Also you probably need some better guidelines. I'd recommend to at least put one at the top of the head and one at the waist. As for me personally I like to put one at the knee and one at the elbow as well. I'd say it's better to have a ton of guides and to slowly parse out the ones you don't need than to have too few guides and end up with a great amount of resizing.
