Congrats! Great design and solid execution! :D Here are a few things you might want to adjust if you’d like to push it further. The connection between the arm and the forearm feels a bit off. The muscle wouldn’t usually appear like that, and with the arm in that position, we probably wouldn’t see the elbow either. The knees could use some adjustments as well. The knee on the character’s left leg doesn’t follow the same perspective as the leg; it’s drawn more like we’re seeing the leg from the side. The knee on the right leg also looks a bit strange because of the overlap you added. Ideally, you’d see the knee shape on one side, and on the other side, the connection between the thigh and the lower leg. The “T-line” is usually a good guide for that transition. As for the rendering: Nice work! I only tweaked the lighting slightly. Since the light is coming from a 3/4 angle, the side would be lit while the front would fall into shadow (though not too dark). When painting, it can help to think in terms of simple forms like cylinders, spheres, and cubes. That makes it easier to understand where the light and shadow should fall. Hope this helps, and again, great work!
