My pre-hormone breasts (ok beer moobs) were more of a delta shape than round shape. With your scar fading, you should go in that direction. You are just a little rounder than completely normal male, but believe me I have seen far far worse on cis males. I might add that one problem I have looking, is that I am trans and know you are too, so others who are cis will not really see it as much as I do.
