The Greek statues were usually of gods or goddesses and had enchanced features to made them look more beautiful. While the Roman statues were closer to the truth on the way they looked. However the Romans also made busts (which are sculptures of just the head) which were designed to make the senator of which they were of the look very serious and very masculine. The Romans also had mosaics and painting which were very similar because they would just put mosaics on the floor and in the wall was a painting which could look the same. The Roman mosaics and paintings were usually images of events or important people. The Greeks on the other hand did not do painting or mosaics. They had amphora (which are basically big jugs) on which they would paint images of myths or important events.
