The bottom of that AAV needs to be 4" above the horizontal branch drain (IRC P3114.4 and see CodeCheck figure below) … unless thats an optical delusion, it would be illegal …
Also looks like an incorrect pipe fitting for the left sink, and it might be 1988 ABS pipe from the ASTM designation. There were problems with some ABS pipe between 1984 and 1990 ... not really sure thats the same pipe though.
