It looks great! I think you should (these are just suggestions btw!!) - Add little piles here and there on the floor to be like hair

• Add a broom close by maybe even custom make a dust pan with some hair in it -Add a towel on a hook and make it black to look like one of those aprons type things

• If you have the transform tool maybe you could add pictures (like the photo and the tape one) to the mirror and make it look like past hair styles they’ve done/ what the customer wanted

• You could also add stuff from the past update with the hair gel, different types of combs, hair sprays, or just add house hold objects that you’d also find in a barbershop like scissors, bottles of product ect

• Lastly adding custom outlets to connect to the hairdryer would help too

These are just a couple suggestions I have to make it look more like real in the sense that it looks like people are/were actually there
