I think You achieved a good effect with Your picture. The model looks nice and I like the pose, the fact that the top and the bottom of her bathing suit match shows a lot of consideration on Your side. I like the backround too, very much monochromatic, not disturbing at all and it goes well with the colors she is wearing. You show good control of the depth of field. I think the image would be much stronger if You included some green vegetation in the scenery. I know it is hard especially in Lima, there is nothing there but rocks and water, especially around Miraflores.
