The art nº2 (red moon) background is very simillar to the prop I had for this exercise, but to challenge myself, I not only studied another color palette, but made the bat different from the original; therefore, the art nº1 (Batman Year One Fanart) is 100% my own idea and design.
I also tried to learn tools that weren't taught in class, so I could achieve effects that were in my mind while doing the pieces and it was extremelly fun.
