help me with shoulder asymmetry

[abvzxc]

When I pose on the back camera with a mirrored view, my physique looks ideal. But on the unmirrored back camera, the asymmetry looks terrible. On the front camera, you can't see any asymmetry at all. Also one shoulder is bigger than the other, and when I flex, one bicep is bigger too.
