"Self Portrait: Windows" colored pencil. 14 hours. currently hanging in the SRQ airport ( 10 in x 16in)

This self portrait was based off one of my senior photos. I plan to enter it into the SRQ art contest. The most difficult part of this was getting the textures and colors in the windows. Similarly, the textures in the shirt and jeans posed a challenge. I think the most successful area of this piece is my hair. If I were to redo the piece, I would pay more attention to the cheek/mouth area of my face, as well as my eyes. Below are both pictures for comparison.
