I'm way late on creating this thread but I did save my work throughout the process of creating it at various stages.
I decided to do a splash of Zed, one of my three favorite champions and, in my opinion, the most fun champion to play in the game by a long shot. I also started working on a splash for a skin idea but I won't be able to finish it in time to submit it.
Initial Drawing
Progression
Early Values
More Value Refinement and Tweaking
Sketch changes and early color
Color refinement/rendering
Trying to modify background, make it more desaturated so the foreground stands out
Levels and major changes--got rid of that railing thing that was really creating problems and wasn't working well in general for me. Darkened the guy in the foreground to focus more on Zed.
Basically the final version
