sorry, im trying to decide if you’re joking? your first ever tattoo you want a complete shoulder, chest and arm scene all in one go? i dont think you appreciate quite how expensive, difficult or painful that is going to be and it worries me that you have decided to cover about 25% of your body in one go and yet you have no idea what you want. i would slow down, start smaller, do some research and see where that takes you, otherwise you are headed for a lifetime of painful laser surgeries and regrets im afraid.
We are more than happy to help you with a realistic goal and will give you all the advice you need once you have some ideas in mind. may i ask where in the world you are and how old? x
