I tried different technique than usually. I first painted grayscale picture with all the shadings and stuff. Then I made an overlay layer and painted the colours. This has several advantages, you only need two layers for whole pic, because it’s easier to fix mistakes when needing only one colour.. though technically not a colour but still. And also it’s easier to colour because you don’t need to stress about shadings anymore, and making variations and even changin the colours totally is much easier. But this takes more time, unless it’s just my lack of experience.. might be..
