I totally think you should! But like someone said, make sure to let people know what the style of art you'd be willing to do in commissions, and also what the subject can be (i.e., jrockers/jrocker pairings, original characters...). Of course, also make a limit on what you will do in with the art like digitally coloring, or pencil sketch...

I'd love to commission something Jrock related from you if you had the offer up for people, because I've always been a fan of your Gazette art.
