Add in more colours

When I was able to get a seat in the train, I would try to add in some colours to my sketches. These two ladies came back from shopping were standing right in front of me. I was not embarrassed when I was drawing then as their back were facing me. However, the couple was standing a few meters away but they were facing me. Actually the guy spotted I was looking at them and tried to use his body to cover his girlfriend. Fortunately, I have already captured them on my iPad before he started protecting her girlfriend. Lol.
