Could not resist

Although I was taking pictures of Tones and Textures I could not resist this photo opportunity, I think the main issue with this photo is that the ISO was set at 3200 as the light was very dull however I think dropping down to 1600 or maybe even 800 would have given a better picture. The shutter speed was set at 1/250 sec to capture the singing of the Robin without blur and the Aperture was f8.0 to give a shallow depth of field as was not worried on the background being in focus.
