Vents below the flood level rim of the highest fixture served By the branch must rise vertical until they are 6" above the fixture so yes, the horizontal bit off the wye is wrong, but the way the main is run there is not enough room for you to be able to roll 1/8 bends. As for the criticism remember it was you that asked the questions. Don't get all defensive when you don't like the answers. Plumbing at the level you are attempting is not an easy task. There is a reason it takes us 4 years, 600 classroom hours and 8000 OJT hours to get a license. If you don't get it right the inspector will just fail it again and if you ignore him and don't bother with an inspection, what you have will done will instantly cause problems and.... If you don't do something about the structural damage you did up there the floor and your DWV piping will eventually sag and not drain properly. But what do I know, I've only been at this for 40 years. I think HJ's had his license since Lincoln was president.
One more tip. Nail plates and fire caulking are required to pass inspection also.
BTW, I know I'm a buzz kill, I was an inspector for many years and know what flys and what fails.
