I like them for multiple reasons.
I can look it up and get that one mood it gives me. It helps with disassociation/depersonalization and makes it so I can get back to myself faster.
I also like how I can display certain emotions through it, when I draw I normally draw with my own aesthetic, but when I wanna do something a little different I can for sure display different things with a new aesthetic.
And I just like to look at pretty stuff.
