It is hard to tell which elbow you used, but if it is a long radius one like the others it will be okay. I might have made the first elbow further away from the toilet line if by so doing it would have lined up with the sink drain coming through the floor. Barring that, I might have used a 45 to line up with the sink drain's pipe through the floor. A 1 1/2" tub drain would not pass here, but there it may be okay, but you will still need a separate vent for it. And a "picky" inspector might want the 3x2 "Y" rolled upward so the wet vent is not at the same elevation as the toilet drain, but it may pass since it is being used as a wet vent, rather than a dry one.
