I like the pose, it has nice gesture. The issue is proportion and 3D shapes. If you think about the neck as a tube attaching to the torso it will give it a more 3D look. That tube will also connect to the skull. Then when you add your anatomy it will feel like a good connection. Pay attention to your perspective too, the arms feel flat because you didn't indicate enough overlap. I hope this helps :) | Artwod Feedback
