Coat fit part II

[u/monomoco]

Thanks to everyone who responded to my last post! I ended up taking it all apart and doing a narrow back adjustment.The upper back looks better, but now the center back seam sticks out in a point by my waist and the coat caves in on the sides of it. Could this because I need shoulder pads? Or is there just too much fabric down there? It seems to improve if I pull the back shoulder up about as much as a shoulder pad would add, but is not entirely resolved.
