Quick Sketch art of my uncle

Hello everyone
It's my pleasure to be back here to share my today's practice with you all. As you all know, I'm very passionate about be good in scribble art and I'm glad that gradually, my skills are growing. If you have been following up my post, you will witness and testify the improvement.

Today, i made a sketch art of my uncle who have been so caring to me whenever I'm in any challenge. I used too red pens i.e ball and switch tip and a cardboard paper of size 12 X 16 inches to create this art within a duration of 40mins to 1hrs. It took me such duration due because of the size.

Step by step shot
