Hey there! I was actually doing a paintover, and it was pretty much what Woj already mentioned to you. :) So I decided to focus instead on suggesting a more energetic pose. The way the character is holding the weapon doesn't really convey that sense of strength. Ideally, the heavier part of the weapon should be supported with an underhand grip (with the palm facing upward), instead of holding it the same way as the other hand. By doing this, I think the weapon would also look better if it were tilted, which would help give it a stronger sense of weight. I'd also make it larger so that its size feels more proportional to the character. :) Otherwise, having a huge character with a tiny weapon... probably wouldn't be ideal, haha. Hope this helps!
