Need help/advice on arms

[rough quest]

Youre lacking all underlying forms of the body (not just the arm).

I suggest you reference and learn anatomy as youre still a beginner.

If you cant find a specific ref photo, take a photo of yourself doing the pose to get a better idea

Do you have any suggestions by chance?
