This is stunning, I never knew it's very possible to lighten the pencil by gently erasing some of it, I thought that there was maybe a different pencil for that. But the fact that you used just one pencil and finished the sketching and the painting in just one hour is so extraordinary.
The use of colours was precise, didn't exceed outside the sketches which made it very so precise and spot on.
Splendid job there buddy well done.
