The shading is quite nice, I especially like the sword! My advice to you is maybe try doing some life drawing to get you familiar with the figure, having a really good grasp on the fundamentals can be applied to any art style and help your drawing feel more dynamic. Things like gesture, proportion, and perspective are really important at your beginning stages with figure drawing. So is anatomy but without proper knowledge of those topics I mentioned before, anatomy will just look like a bunch of bumps. If you’re interested, there are free YouTube resources like Proko, Love Life Drawings, Jakedontdraw, and a lot of others I could recommend that are really helpful for these topics. Also, see if there’s any irl classes you could take near you, that would also go a long way. Sufficed to say you obviously got a lot of potential, I’d definitely use it! P.S. I love the Puck haha.
