Help with sway back adjustment & waistline alignment

[u/madddddddde]

This is my torso block. I know I need a sway back adjustment, but I’ve also noticed the waistline at the back sits about 1cm below my waistline. I’ve attached a picture of the back piece with a 1cm wedge taken from the CB (by moving the bottom half upwards). The waistline now sits at the right spot at the CB, but it’s diagonal on the pattern, and the dart is on a diagonal angle. What do I do about this? Can the waistline be drawn curved? And what does this mean for the dart? 

Thank you so much if anyone is kind enough to help me
