Hey there! I like the characters! But in general, what I would do is push the gesture of the pose a bit more so their personalities stand out. For example, notice how in both characters I emphasized the tilt of the shoulders and pelvis. You can also exaggerate the tilt of the head a little. Notice that for both characters, tilting the head helps give them more personality. The movement or position of the hands can also help communicate part of their personality. Sometimes it's good to think of the hands as characters themselves, so to speak. Hope this helps! P.S. Don't be like me and look for references for the clothing so you can see how the folds actually look. I drew it from imagination, and I'm sure some of the folds aren't entirely correct, haha. P.S. 2: Sorry if the character on the right isn't a woman, and therefore the pose doesn't really fit the concept of the character, hehe.
