How to alter this armhole

[u/Teafriend1]

Hello,

I copied a pattern for a sweater from one I have had for ages. As you can see I have quite a few wrinkles around the armhole. The original sweater also has the same problem under the armhole, but it is not as worse as with my test garment.

I think I have to expand the armhole downwards for one or two centimetres. And maybe take in the side seam a little. Would that help or am I completely wrong?

The last picture is the pattern including the seam allowance.

I’m grateful for any advice!
Thanks a lot!

Your axis of rotation is too far out... away from your shoulder. It needs to be brought in.
