Professional rough-in

Here is the new layout for the basement rough-in:

I don't know where to start except to say no. That was done by a plumber too?

Terry, HJ,

Do you see any issue with this setup?

Everythings wrong with it. There's no vent for the shower or the toilet and whatever that line is coming in after the toilet, if it's a vent then it's flat and not to code and if its part of a wet vent it's on the wrong end of the toilet and the shower drain is a 3/4 s trap with no vent and the top picture has no toilet vent and the list goes on and on. Nothing there meets code really.
whoever is doing the work has no clue about proper venting or plumbing practices either for that matter and you can get all pissed off at me if you want but I'm trying to save you money, time and headaches down the road. You can do it right or you can do it again and again and again.

The line after the toilet is a wet vent line (for the laundry sink and the bath sink) which will tie back in to the old copper vent. How could a vent be on the wrong end of a toilet, I'm not following, it is downstream? The drain to the left of the toilet is not vented, it is a basement general drain, not a shower drain (that is why it has the primer line). The drains in the top picture are a bath drain and shower drain, both of which are vented, the lines run to the left wall in the picture.

The laundry sink can not be used as any part of the wet vent system. Only bath group fixtures can be wet vented. That line should also have been before the toilet so that the toilet wye is washed by the fixture(s) above. The floor drain is not vented and the way the fittings are laid up you have created an s trap there. Where does that horizontal that is above the floor drain wye go?
