adding in a second sink

I added in a second sink for a vanity, it has an 18" cabinet, 24" vanity, 12" drawer bank and another 24" vanity from left to right. The wall is a 2x6 plumbing wall with a 1 1/2" drain galv. 45'd to a 2" vent, the vent is for a toilet downstairs. The 1 1/2" drain may or may not connect to the 2" vent. Is it ok to connect it like how I've done in the attached image?

Welcome to the forums!

Your image didn't attach correctly. This may help

Not sure what you had planned, but if the 2" pipe is a vent for a downstairs toilet, you can't use it. All (most?) codes do not allow wet-vents between floors.
