Old man with funny face

Hello everyone,I'm happy to drop this piece of mine,it's a old man with so much wrinkles,it made this piece intricate and more interesting to me,the expression on his face and his funny mustache.

I started this work using a different sketching techniques,leaving you to wonder what I'm drawing,the outcome and feature of what I'm drawing,the sense organs are not sketched out from beginning,I just sketch out little place and detail it,I call it the suspense sketch😄 
 I enjoyed working on this piece as well as the outcome and I hope you like it and enjoyed the journey,I used brown,blue and black ballpoint pen and smudging shading techniques,

Thanks for checking...
