Prove yourself as the best artist for the week

This is a quick sketch I made after looking at a reference but tried to draw from my head. Sometimes I do this ones in a while to see how strong my photographic memory can be.
Artist who do this are really gifted because each time I try it I always tend to portray another character in my sketch. I draw from my head most times but then it’s just a random subjects, the only time I drew from my memory and it turn out to be someone in my hostel room was when I was in high school. After I finished the sketch everyone started pointing fingers towards the person it looked like, at first I didn’t realize the drawing looked like him until I looked at his face and then saw the resemblance. it was so funny and exciting to me.
I just had to take the glory and acted like he was the one I was drawing from memory, he was so happy to see a sketch of himself.
This just tell how powerful our brains can work with our hands.

This sketches I started it with a freehand sketch, showing a faint line before proceeding towards adding more shades to the work.
