This painting artist are famous not just because is his skill of drawing. But also the technique he use on to the drawing as well. He successfully use the reflection concept on the his painting and make a illusion on the painting. He use the crystal ball to help him reflection his face on to the painting. This skill we can use on many area of art like painting, SOS or sketching. He use his own hand holding a crystal ball is to increase the distance he with the painting. Just like he want to draw himself in the painting but is use the indirect way of doing this. The skill of sketching is professorial. And the technique he use really expired me.
