Hey there, I want to say for your first tattoo you are 100% going in the right direction. I have zero interest in getting tattooed by Kiku, but his work is damn good. You will not be disappointed at all and he is super nice to his clients. I was getting tattooed at Invisible and he had a customer. Very awesome dude and the shop in itself has GREAT vibes.
I wouldn't worry too much about it because your are aiming to the top for your first. At this time there is a wealth of information via magazine and instagram. You made a good choice, don't get cold feet. I kept getting cold feet for over 10 years. Stick with it, you're good man.
