A very nice picture, DOF is just as it should, colors are natural and bokeh is great here, even if people (in the forums) does not like bokeh so much for this lens. I was hesitating to buy it vs 1.4D for my D70. My choice is made now. I'll take the 1.8D. Well done Sergio.
On my first quick glance at the thumbnail, the colors and textures of the table covering made me think of the beach. Treasure chests sitting in the sand with the water lapping up next to them. Maybe in an abstract version of the photo. As is though, it is very nicely lit, making for great color rendition and contrast. The framing seems a little off maybe the one in the upper left should be completely in the frame.
