2:1 ratio. On the left I put a bright, yellowish toned light, and on the right, a dim(side light), cold toned light. I like the warm and cold featured in this picture.

Neutral toned dramatic lighting. I adjusted the light on the left to neutral tone and increased the brightness to emphasize his facial features, a result which I like! I also like the colour of the wooden box under this lighting.

Cold toned dramatic Lighting. I moved the light source to the left even more to create more shadows, as well as changed the light to cold toned. I want to show how he is drained from battling his thoughts by showing a pale face of his. The shadow covers his eyes and hides his miserableness.

At last, lot of thanks to the model, Austin!
