FLCL is one of my favorite anime. I didn't find it through Adult Swim as many people did (I wish I'd found out about it that way, it sounds so cool to go in not knowing much), I just heard someone talking about it on social media when I was about fifteen.
On my first watch, I didn't like it much. I thought the animation and art direction was great, but I expected that from GAINAX. I loved how much ambience is added thanks to the soundtrack by The Pillows was. And ultimately, I ended up revisiting it half a year later with my motivation being the soundtrack.
On that rewatch, the show clicked with me. The way information is deposited was really intreguing to me as a fifteen year old, and has stuck with me to this day.
For my 23rd birthday, as a sort of present, my best friend Lexi watched FLCL with me, and that experience led to me making this illustration.
