Remove "red rose" if it adds too many. It's only needed for her brooch and sleeve flowers to gen correctly but SD tends to add a lot of roses to the scene as well.

You can remove "heart facial mark" if you don't want it to show.
Might need to add "tiara" to the neg. Or put something else in her hair like "hair bow", "hair flower"
Sometimes you get an extra heart facial mark for free because SD likes symmetry. Try a different seed or variation seed, or you can inpaint it away.
