Text Sketch

The project I am now working on consists of translating text into image. The text I received explained an oil painting of a man with a stern, cold look on his face. He is half naked, and constructed with a limited color pallet. I have decided to recreate this piece in an acrylic painting.
To start off, I looked through many photos online of men so I could study their poses and facial features. Realizing the best way to create my own meaning, I then used a male model to pose for me (i.e. my boyfriend). I took many pictures of him in attempt to capture the essence of the painting. I feel the pictures turned out well, but I am still sketching to try to portray exactly what I want. I seem to be having trouble finding the meaning to "gloomy" which I wish to express in the eyes; hopefully, it will come to mind soon.
