Home sick but still making the art

I have one hell of a chest/head cold today. Slept until noon and went to bed at 8. Just kicking my butt. And yet... I can still do the arting. Here is a sketch I did some time ago inspired by This Northern Boy over on Instagram. He does amazeballs work. Anyhow... figured I would do some experimenting with colours and such. Feel free to crit on anything. I can take it. I want it actually. Painted on iPad Pro 12.9

Cheers
