Walking, 1st animation:The furthest arm seems too close to the torso. Doesn't show enough at the peak of the swing.
The legs look too far apart. The places where each of the feet step are too far apart. (I'd change the furthest leg)
The closest arm moves too much into the torso. The upper part moves way too much, looks as if the shoulder was unhinged
The arms seem of different lengths, the right one being shorter than the left one.
Walking, 2nd:Again, the paces seem too outward, and the right arm seems a bit shorter than the left one.
Moving against wall, 1st:I think there is a small change of perspective between the character looking forward and the character looking backward.
Trace a line that passes through both feet in the two instances, and see whether they're parallel enough.
Moving against wall, 2nd:The right foot bugs out a little at the end.
Choking out 2nd:The talon of foot that stays back has to go up as the foot bends. It's anatomically impossible to leave the back foot completely planted on the ground when you kneel forward (try it out yourself, you'll see you can't, even if you wanted to
) To show that it does, you should have a lighter gray color for the shoe sole.
The mass of the legs seems to vanish as the character kneels down. You should have the upper part of the right leg pop out forward to avoid this. (on both the first and second animations)
Climbing:Again, there is an apparent loss of mass as the character hunches over (become a little dwarf in the last frames).
Colors:I advise you don't use dithering (doesn't look good in such low resolution), and instead use a lighter color than what you have for the jeans' shadows. (or maybe add a third one as middle-ground)
Overall, cool and interesting animations
