A question on do you have a suggested tutorial to watch how to color webtoon type art?

I want to learn how to color the blend where to put the sharp edge and soft edge shadow and where to put the details and so on. I am learning coloring in digital, these days I barely see OG tutorial like before where you can learn. Way back in 2020 there are still a reliable tutorials but recently there are a lot of artist rise with decent style but lack tutorials. If you have suggestion I would be gladly to accept where can I watch this thanks.
