That must have been a pretty bizarre conversation. I try to draw drunk, all the time, but it's such a bad idea to be honest. I always either get bored or get too sloppy. Alcohol isn't an inspirational drug for me haha. While I was in Amsterdam however... well that's a whole other story. I tried to draw rainbows with a pencil. As in, a 2B lead pencil, does that even make sense? It seemed to at the time.
Ah I'm the polar opposite. I don't even try to draw drunk, it just happens. It's always with excited apprehension that I turn my PC on the morning after when I see my tablet is still plugged in.
The worst part is that when I'm drunk I don't consider naming files properly, and in the morning I'll find 14 images all named 'Untitled (1).png' 'Untitled (2).png and occasionally something along the lines of LolImAFiggit.png
I keep them all though, I have folder dedicated to them. It's like a scrapbook of photos taken by myself when I was a baby: I don't remember any of the photos being taken and don't understand what half of them are.
The quality generally ranges from amusing doodle absolutely undecipherable or vastly inappropriate.
On very rare occasions I come out with really surreal pictures that i'm actually glad I decided to draw whilst drunk.
