Any fit connoisseurs available to diagnose some M2M shirt issues?

[The Dirty Pigeon]

Hey everyone. I'm a short guy so off the rack isn't a good option when it comes to dress shirts unless I compromise on details like collar size, sleeve length, etc. I've been ordering made to measure shirts from Luxire and I'm working on a proper fit for my dress shirts but, as you can see, I'm not there yet. I want a nice clean front and back with as few wrinkles as possible. By looking at the attached photos, can you tell me what areas I should be focusing on adjusting for my next shirt order?

My observations are as follows: The shirt doesn't feel tight to me and only feels restrictive when I reach forward - there's some pulling across the upper back (yoke) between the shoulders. However, the obvious lines from pulling in front of and behind my arm pit might suggest that either the arm hole is too high or chest size is too small? Also, something I notice is that the top shoulder seam runs at the front of the shoulder instead of the shoulder top and there's some wrinkling at the top of the shoulder. Does something seem off there? It's fully tucked in but I'm still getting some billowing from the middle downward and I'm not sure why.

I'm looking for advice on measurement changes that might help for my next shirt. Any help or guidance you can provide would be greatly appreciated. Thanks!
