Vampire_rose

This is my first color silkscreen printing project. I saw an event that offered color silkscreen printing, so I drew a white-haired character and put it on (do not use without authorization, please cite the source if you use it, I am the artist). The inspiration is Della Camellia.

However, this wasn't very successful. I'm not very good at circuits, so it's a bit rough. Even simple assembly isn't enough. I used JLCPCB's simulation, but the result seems different from what I imagined. Oh well, I was mainly aiming for the aesthetics. It would be great if an expert could point out the circuit errors. My original idea was for the bat's eyes to flash alternately, slowly like a breathing light, while the other parts remained constantly lit. I just drew
the board outline in CAD and imported it. There were a lot of minor hiccups during the process because I wasn't very good at it, but it finally lit up. However, after soldering on the double flash, it stopped lighting up, I don't know why.
