I was tasked with creating the game cover and the soundtrack cover for the game Sine Mora by Digital Reality. I was given pretty free hands to do whatever I wanted, the only direction I got was that they didn't want it to look like a traditional game-cover, they wanted it to look graphically designed, artistic and original. I think they turned out pretty good, and I had a good time with these!
Then I was tasked with coming up with a design suggestions for the UI. Not everything was used, but I was pretty happy with what I made, clean and easy to read.
