Great Work! Your composition is complete! This final part is optional but could be informative for anyone whos interested in learning about color work and Gradiant Maps to give your work some interesting colors. To explain Gradiant Maps are like a Black and White filter but insead of Black and White you can control the colors involved. Go ahead and play around with it! Gradiant Maps can be a great tool for adding some great and vibrant colors to your picture as a whole, as well as giving it a overall more cohesive look, which is very important in works like photomanipulations, not as important in something like this but still can add to the feel of it! I also added a levels layer for some added contrast. Below are the settings for my adjustment layers, with my gradiant maps I usually reduce the opacity down to below 10% to add subtle changes. I would encourage you to play around with these to get a hang of how they work and how to use them!
