Thoughts on what needs to be done/redone.

I just had a guy “wrap up” this dry wall in my basement bathroom. The more I look at it there are some concerns I have, especially with the ripped paper on the ceiling above the shower (pic 1). A lot of the joints are done poorly, can these just be mudded over and feathered/sanded again?

Regarding the ripped paper in the shower ceiling, does this whole piece need to be ripped out and replaced? Also shouldn’t this ceiling piece be green board since it’s in the shower? The ripped part is raised, as if the sheet is broken.

I feel like I need to have him come back if the job is to rip out and replace. If it’s just mudding, sanding, and some primer for the ripped piece I can manage myself. But it’s a brand new room so I really want it done right.
