Wow this is a really interesting technique to me! You see so many people doing the reverse - sketching in pencil or pen and then scanning in to color digitally. I am not sure I have seen anyone using this technique though, sketching on tablet to begin with then tracing onto paper to color with watercolor. That is pretty interesting! The finished portrait turned out great. Love the splotches of color in the background and your intense expression. Thanks for sharing this process! I want to try something similar now :)
Much love - Carl
