Well spotted anc captured, as David mentions the Robin is a bit on the dark side, however the histrogram was showing you got the metering spot on imo so there is nothing wrong there. Have done a quick edit and will remove if you wish. I ran it through Neat Image to reduce any noise and then adjusted levels, vibrance, brightness and contrast. Also cropped it to portrait although a bit more room on the top might have helped it a bit more :shrug:
