The construction of upper body is fine but I think you got a bit lost when you drew lower half of the body - the lower part of the torso is a bit too long. Making fabric wrap around the body and adding few folds could improve the drawing greatly, too. Consider gravity and whether character is tense or relaxed when drawing limbs. (Take this with a grain of salt - my anatomy is not the best).
idk if the lower torso length is the main awkward bit, maybe tuck the sit of the hips a little and let the thighs come forward from there so the seated pose reads before you wrap more folds
