Spray Paint Art Inspiration

I found this YouTuber Casey Does Everything who does long form and shorts of spray painting. His YouTube shorts are what got me interested - he does awesome paintings that look almost impossible but he makes them seem easy.
After several months of watching his stuff and others, I was inspired to give it a shot. I bought a bunch of spray paint off Amazon and some poster board, and essentially followed what he demonstrates in the YouTube shorts.







They came out pretty good if I say so myself! Still learning the techniques though - it looks fairly easy when Casey does it, but there's absolutely some real skill involved in getting the planets to look round, the shading right, and not over-spraying.
The best part? I was able to teach my 9-year-old niece and my sister how to do them during a recent visit. There's something magical about creating these space scenes together.
Supplies:
- Spray Paint (Various colors) https://a.co/d/eO5Ls4H ($6-$10/can)
- 25pcs 11x14" poster board https://a.co/d/41lEf9M ($14)
Next up: I want to try some of Casey's more advanced techniques, maybe some cityscapes or adding more detail to the planets. I tried adding rings to the planet but it didn't quite work.
