I decided to go a little extreme today and only use textures for the background (Which was originally sky).
Processing:
Levels
A little desaturation
First grunge (the rust) - Hard light (masked subject)
Texture - Scratches in metal - Overlay (24% opacity), masked face
Third texture (dirty glass) - Overlay 56%, masked face and hands
OMG .. this is just plain wonderful .. the stance, the texture, the process with your colours .. this overlay side challenge is bringing out the most awesome work .. :)
