Faulty lines : The Joker

Hello Steemians!!! I sketched this ball pen sketch a couple of days ago. I was just experimenting with my sketching techniques and realized that i have never used ball pen for sketches. This is my first sketch with a ball pen and it took me about an hour to complete. I couldn't erase the lines once they were drawn contrary to using pencils, so you can find lots of faults in it hence the name Faulty lines. Overall, it was a new and satisfying experience using ball pen.
Thank You!!!
hope you like it.....
