I received a 180mm portrait lens for my Mamiya last week and this photo is one on a roll of my first attempt. Wasn't expecting much just wanted to get a feel for it. The first half of the roll was taken in low light and were very under exposed. The second was much better. This has been cropped.
I know....a little too dark under the right eye and the bright patch to the left is a little distracting.
You are a tough audience, I'll try and do better next time.
