very nice. the colour look very natural.. using a telephoto such as 80-200 F2.8 at a speed of 1/250 is good for candid.. but i think if the subject dont move so much. you could slower the speed. the catch the ambient light in extreme low light condition... hmm. had you try to push the iso .. 1000-1600 maybe.is it too high for nikon? than convert the picture to bnw with noise , hehehe.. just my opinion..
