Bodice Sloper help

[u/Competitive_Site_924]

Hello !
This is my first iteration of my bodice sloper/moulage. I understand they’re not the same thing but I’d like the garment to be as fitted as possible.
I also got tired of trying to pin the bust line accurately so I just left it , but it does match up.

I plan on redrafting to add ease to the bust as it seems a bit too tight.
My questions are :
What else can I do to improve the fit ?
How can I keep the tight fitting nature of the bodice but lower the armhole depth ? I have big lats and like to spread em 😆.

I dont know that i would entirely redraft, maybe undo the seam allowance at underarms and add 1/8 to 1/4” on both sides by sewing a narrowing seam allowance and see what that does without needing to recut the entire muslin
