Barbarian Jack

I'm playing an occasional game of DnD with some friends and i'm playing the role of a barbarian and this was supposed to be a joke for them so i'm not sure why i'm even uploading this
Also, this is my very first time trying to draw muscles and despite trying my best looking at different pictures to get an idea, i'm pretty sure i made many mistakes, i'll hopefully be able to see and fix them if i try again but for the time being, this is the best i could do

( and yes, almost no effort went in the background )

Still, i guess some of you may have a laugh out of this?
