You have magic hands and touch. Great technique and skill, you made it looks so easy to draw an excellent work like this. I learn a lot from you. One thing I realize is that nitram is a great tool. It is easy to erase, lift off, fill in and spread smoothly like vine charcoal while it can be as black as compressed charcoal. Though retaining to paper is not as good as compressed charcoal but that is manageable. ❤👍
