This is very good Endosphere my only suggestion would be to see all their faces in some way, mainly the two near the scale facing the wall....perhaps face them and work on their expressions, no girl likes to face the fact they put on pounds over the holidays lol the girl sitting by the coke machine perhaps turn her head slightly like shes laughing at what the other girl is saying....these are just my suggestions to work on the action of the peice. All in all its a very good pic and well done!
