First off, very good work! I think there's some three-dimensionality that's getting lost in his arms crossing, making it look at little more like it's cold outside. I did a fast paint-over and looked at some crossed arms references, then I pushed those arms up, really bringing them to the forefront of the image. When it comes to emotions in a scene, a part of that can be conveyed through lighting, so I've also added some shadows to give an idea of what that could look like, covering half of Zoro's face in shadow, giving it a more mysterious vibe. Hope that helps! Great work keep going!
