“Before doing the painting, first of all try to find the inspiration or something that you really want to paint, as for portrait realism attempt, we have to observe the subject, sketch over so many time, until we finally catch the essence or the mood, you can do traditional at the piece paper first, try not to trace but when you’re ready, you can directly use the tablet for the efficient use and time, some random sketch with pencil, Hyde is really interesting subject to paint, since from time to time, he always change his appearance.”
