Toilet and Shower drain / vent question (annotated pics attached)

[JHorack]

right now I have a shower drain that vents to the roof then drains via the toilet drain pipe. (this will all be in a soffit)
I had to get a little "creative" with the connection from the 3" pipe to the main. I'm wondering if there is anything technically incorrect with it. Thanks again for your advice!

You used clear primer, or is this an incredible mock-up?

The lower left PVC fitting looks a little misaligned on the upper side.

sorry, should've mentioned this is a dry fit. I haven't cemented anything yet

It looks pretty good until you get to your 3" vertical which looks pretty wonky. Don't be afraid to use a 45 to angle over to the vertical to get to the 90 that drops down.

Thanks Terry! That tip helped tremendously. I took off the 90 and used a 45 then a 90
