Hi. I think you're doing a great job with your lines of action, and clearly showing what the person is doing in each pose.
I think that the proportions are part of why they look wonky. Keep in mind that a solid 3d person has to fit inside the 2d shapes on the page. Also, I looked at some of Reiq's gestures, and I think he's lengthening the legs slightly and narrowing the waists of the figures for a stylish look. You could try that in some of your drawings, if you like.
Also, in only a few of your drawings, the figures look off-balance. It might help to imagine an invisible line from the pit of the model's neck to the floor, and then mark where the feet should be, related to the neck, before you draw the legs.
But in general, I think your figures' proportions and balance will improve as you keep drawing and keep studying people.
Best wishes, and thanks for showing your drawings.
