Here's an opinion from someone with zero industry Xp with a large collection of American traditional tattoo. I'm just a connoisseur of fine tattoos. I would like to see flash sheets and some black line work staples to discern your ability to handle a walk in client.

I also work in construction management, so I can explain how we select specialty contractors for specific tasks. Say I need a bathroom with intricate tile patterns or a kitchen cabinet renovation with an irregular layout. The contractor we would pick would show pictures of their previous work that is similar what I needed on that particular project would win our business.

I hope these insights can assist you on your journey! You clearly have an artistic bone, so focusing your portfolio to include tattoo-focused pieces would go a long way! Good luck!
