Sketch 2 - Black and White Guy - Digital Draw

Hi everyone, today i was trying draw with photoshop. I am a beginner in this type of drawings, and I'm learning how to draw with wacom tablet, so, after about two hours of work and youtube tutorials, this was my result:

It was a bit complicated because I discovered that it is nothing like drawing on paper

It should be noted that I like to draw Asian features, because I think they are more delicate and fine.
