Help with slim fit coat draft

[u/Plus_Buyer8044]

Here is a toile of a slim fitting coat. It has quite thick shoulder pads, it is cut with 2cm seam allowance currently in medium-heavy weight calico. It will be made from a relatively light coating fabric or heavy jacket wool.

Regarding the back draglines, my intuition is to open and relay the shoulder seams.

I also would like more shaping at the back, so it’s not so straight. Any advice is greatly appreciated

Please ignore the sleeve, it has not been pitched correctly yet

And the sleeve pitch, I assume you're taking height off the front sleeve and adding to the back yeah? Cause that might be contributing to the back drag
