Designing an illustration for Etsy store (dogs/punk rock)

I have an Etsy store selling custom-made patches and sewn goods, i.e. dog and small pet beds, bags, etc. with a punk rock aesthetic, coupled with cutesy animal products! Focused on selling items for dog owners and small pet owners, like rabbits, hamsters, and hedgehogs. Patches typically feature classic and modern metal bands and aesthetics related to those styles. I would love to have a small, somewhat detailed illustration of my dog, a blonde Yorkshire Terrier. I want to sort of use him as the mascot for the store. But because I like to make things that aren't traditionally "cute" and more on the metal/punk/classic rock side of things, I think it would be fun to have this cute dog be somewhat "edgy" for lack of a better word. It can get pretty goofy and out there, I like goofy things! Something done in a sketchy, rough style with a furry blonde Yorkie with maybe some eyeliner, or earrings, or even a mohawk or huge glam rocker hair would be pretty funny. He could be wearing a leather jacket/vest or whatever looks cool and fitting. I would be using this for my profile picture on Etsy and for business cards included with my shipped goods. Something akin to Hillary White's work on Redbubble: [login to view URL] would be pretty fun!
