I am currently working on that last sequence, where the player sees a human figure in the distance (their own reflection), that mimics the player's movement. Although blurry and minimalistic, the character design is essential in this one. Due to my limited skills in drawing, I have been struggling to come up with a professional-looking character.
So, I have tried a basic sketch of the human figure. This is just a quick and very rough sketch so that I can quickly import it into Unity and see how the overall mechanism works out. In the video, you'll see the character mimics the movement.
