GAHHHH

I painted a pretty ok-looking cloud few days ago. Today I wanted to add some blue to the shades to make it less grey-and-heavy looking. I ended up ruining the whole painting. Because it was on canvas, I do not have any back-up copy. I didn't even take a mid-way photo. Heck, I can barely remember what it used to look like. I feel like I'm going to cry now.

It's something that happens in art, I know, but it doesn't make it less frustrating when it happens.
