>>14402200gesture is ok, proportions are fine, good lower leg and foot shape, although the calves shouldn't be as pronounced. Zoots have no butts to speak of so the upper leg and the hips are a bit too human.
One of the most glaring things is a sausage man anatomy - zoots don't really have pronounced muscles, they're flat, see picrelated. Even if you were trying to draw a human arm, you ended up doing neither because the bubbly shapes you keep making can actually make picture look worse off. Take a look at the abdomen - it looks like two fat folds. I get it you were trying to give the body some natural flexibility, but it should be generally a single curved line.
Back could use some work - look up spine shapes, but generally push the bottom part a bit as it the tail base is too wide. I guess it's fair to say the entire construction is fairly disjointed and while individual parts are fine, it doesn't work together.
Last thing is the head shape and composition - look at a stoat reference and you'll notice head should be more slender, triangle-shaped rather than block-shaped.
The eye should be moved forward and nose bridge should be pushed to the left. Stoats don't have chins either and the distance between the nose and the mouth is too big - squeeze the front part and shift the eye so the stoat doesn't look like she's got the Down's syndrome. Find a picture reference picture and try drawing the actual animal first a few times until you can emulate the actual animal before adding human features to it.
Use references. I can't stress that enough. If you don't try to copy what you see, you'll end up doing a mashup of random body parts cobbled together in a random fashion.
