“Break-time” painting

I’m taking a break from painting the portrait to let the oil paint dry for a couple of days. Here’s what I’m painting instead, three restaurant workers taking a break before the lunchtime rush in old Havana, Cuba. I was aiming to take the photograph without them noticing me, shooting from the hip but the woman caught me, though she didn’t seem to mind too much. I have just laid in the first colours, lots more detail to fill in. Its a small painting, only  30x30cms.
