From time to time I do traditional paitning as well. especially when my pc is rendering a new video and can't be used for art. Most of the time I do scetches and marker stuff then, but I also love oils and gouache.
While painting with oils is quite stressful, all the preparations and cleanup and smell, gouache is a nice way to go. Water despensable colour which behave a bit like oils, but dry much faster. so, long story short, painting is awsome!
