What's working: Strong character design with a clear narrative. The color palette is cohesive and the suit detailing shows good design thinking. On your concerns: You're right about the gesture. Shift the hips or lean the torso to compensate for the suitcase weight. Even a small change adds life. The upper arms read short relative to the forearms, making them look stubby. The suitcase hand needs work: the fingers feel flat against the handle rather than gripping it. Study a few handle-grip references. For the backpack, add panel lines, vents, or a hose to break up the surface. What I would do: Try 2-3 quick thumbnails of this character in different poses before redoing the final. It'll help you land on something more dynamic. Hope this helps :)
