During this exercise, it was a bit of a refresher for me, being able to reconstruct this photo using Photoshop, I was able to manipulate some of the layers, by utilizing layer masks and soft brushes i was able to add different artificial lighting sources. the Layers I altered were the following: Ear Minor Highlights, Random Highlights, Small Highlights in breather and Mask rim, Left vents, Back fill, Back Highlight, Top Front, EYES, Base/Key 1.
Nice job, I like the low key nature you took with it.
