I made this right after getting photoshop for the first time to test it out and practice compositing. It's not perfect, but for my first project in photoshop I'm happy with how it turned out!
I'm looking forward to experimenting more the software and seeing how I can combine it with other workflows I used before to create concept art or other images.
Scroll down to see addition WIP images - one is just the masked images without any lighting or colour adjustment effects, and one is the finished composite without the final adjustments I added using the Camera Raw filter.
