Your drawing show problems which may be actual or may just be a bad drawing. Every fixture vent take-off must be vertical until it is at least 6" above the fixture flood rim and no less than 42" above the floor of the highest fixture served by the vent.
It would be helpful for you and for us if you printed off some isometric graph paper and/or made legible isometric drawings. The pipe sizes, the types of fittings used, and their orientation are all important information.
I will make a 3d model of the setup, but how do I vent the shower in the basement floor . The vent can only run horizontal until it gets to the wall.
