Hayden Williams is an 21 year old British fashion designer/illustrator. I came across his instragram page and I was completely floored. His sketching skills are impeccable. I personally love his sketching style and how she showcases the celebrity, model, etc, but also brings his own style to the sketch.
Here are a few of the celebrity sketches Hayden has done:

Anna Wintour

President & First Lady Obama

Jay-Z & Beyonce

KimYe

Brad Pitt & Angelina Jolie

David & Victoria Beckham

Aaliyah
