What splendid costumes. I think this is just fine like it is. The colour and composition of the ladies dominate the photograph so that the background is not intruding at all. Having said that I love the rich colour of the soil between the ladies and the shadows over on the right. They may be posing especially for tourist but it's still a wonderful shot.
The lady on the left could do with cheering up a bit though, my doesn't she look grumpy
