Fridge ventilation concern
I never like seeing a refrig installed into such a tight space. If your unit is installed with cabinets surrounding it, the recommended space is 2" all around (never happens). I dont' believe the sides are as critical as the top, your installation is not good for long term. You should remove at least 2"-3" from upper cabinet.
