I wanted to include geometric figures that would be aesthetically pleasing to look at. After spending some time looking for reference, I favored some illustrations of quartz made in vectors and decided it would be good to have them shine like neon signs on the poster.
I loved the ending result, I experimented way beyond my comfort zone.

So I added less grainy effects on the composition.
I also tried many ways in which I could make the quartz figures stand out.
