Hello, I made my first rig animation in blender 2.8, I used Eevee for rendering, and I have a feeling that I can somehow make it better, but I don’t know how, So I thought you guys could give me feedback and suggestions for the future. 
The animation:
The head moves offset compared to the body when the right arm of the rig moves up. Try to connect the head and body together or anchor it?
Very nice animation, but I would do a little more with the limbs that aren’t specifically moving. Like move them just a tiny bit or have them sway.
