Disclamer! I might be wrong...😁 First thing I noticed was the legs. Since it is made like human, we should remember the length of legs(starting from where hips ends and till the feet) is slightly longer than the upper torso and head combined. As for another point... Both calves and feet are of almost same size. If we assume that the leg(our left) is coming outwards or say, is ahed of the other leg. It should be a bit bigger in foreshortening. Both knees are slightly bent, there is not clear weight distribution. We can't decide on which leg our character is putting more weight. Another thing... You can add a tiny bit of solid black shadow under the feet so that if feels grounded instead of somewhat floating.
Thank you so much for the detailed feedback! Your points about the leg proportions, foreshortening, and weight distribution make total sense. Adding a contact shadow to ground the character is also a great tip. I really appreciate your time and help! 🙏
