Looking Good! That's nice that you kept the ISO low. I try to shoot at 100 as much as possible.
Not sure if you shot these RAW/NEF, but I highly recommend it. I shoot RAW and then convert them to JPEG later in post-processing (after any adjustments). The Nikon software keeps all your camera settings, by the way, even if you shoot RAW; and it matches the camera controls that you have in the D7100.
