Headset sketch

Hello everyone,how are you doing,I was bored on a Monday afternoon and tuned to the best therapy which is music and I gave my head set a second look like,yo! Bro,you deserve a quick sketch, although not that quick,HE always come through for me when I'm alone,I decided to add a charger head to it since they are of the same family (accessories) to make the composition a bit interesting.
This is a sketch done with black pen on cardboard,I detailed it with smudging techniques.

thanks for checking,
the processes are below:-
