I really like mindlessly doodling on real paper, it's a lot more tactile and carefree. Doing more precise art on the other hand is a lot more stressful since if you fuck up, more often than not you fucked up for good.

Watercolours are fun but if you wanna try them don't cheap out, I used some cheap dry block watercolour set for this and it looks pretty awful. Use the ones that come in little paste tubes!!
