Okay, a couple of notes, not too bad though...
You installed a sani-tee on its back on the sink waste line vs a wye and 45 or, combo.
The sani-tee connecting the vent at the top is reversed.
You installed a drop in the drain after the trap and before the vent causing an s-trap to be created.
You used rubber Fernco Couplings vs the banded couplings I suggested like the Fernco Proflex series.
