Question about wet/direct vent to stack.

[DIYplumber]

Hello. Thanks for this awesome forum. I have learned so much here by reading.

I am wondering if anyone might look at my attached drawing here and tell me what you think of
the venting ? Sorry if you have to tilt your head to read it.

The bathtub trap goes right to the stack, no vent (or wet vent) but their is a tolite above it, I guess that could matter right ? It used to tie into the diagonal pipe coming down to the vertical stack but I had to move it down a bit and attach it to the vertical (it used to be in cooper so the sanitary t was at a different spot)

I added a laundry standpipe and a sink down there. I am not sure if they are vented correctly. they are close to the slack 1ft and 5 ft.

Thanks
