I actually did this commission earlier last year, just never posted it.
Commission for a family member's co-worker so that he could give it to a friend for his birthday. Actually done for the same guy who commissioned me to draw a different friend of his as a Simpsons character on a card last year.
The person this card was for is a big fan of the Buffalo Bills so it only made sense to create a piece where he was a part of what he loved X3
For this piece, I tried that greyscale painting technique I've been tinkering with.
Side note: football helmets are hard.
