Hey Ryan.
We talked in ur introduction thread, 6 months ago.
I thought u would have got ur tat already.
But u take ur time and that's for the best.
Still, don't overthink it, just go and meet the tattoo artist of ur choice.
All those artists u found look fine, and if no one can figure which is best suited to you but urself, I like Shaun Webber's style the best.
Now regarding the phoenix u showed, don't worry that it may be too much details, the artist will make his own design anyway using ur phoenix as a reference, just like any respectable artist would do, u don't want a tattoo artist that just copies stuff, u want ur own phoenix, designed just for u.
Regarding size, it's on site that u decide, while he tells u the what and what not, and shows on a mirror the design he did on a transparent paper applied directly on ur skin.
At this stage, it will be easier to decide, and tell him it's too big or too small, too much details or not enough, and the quote should be here or there...
If it fills ur whole shoulder and arm from the tip of the collarbone down to the elbow, one color: black, I don't know about the prices in US, but here in China it would cost around 400 dollars, and will last 4 to 6 hours, after 4 hours u may want to come back later to finish, I personally can't take it more than 4 hours, and prefer to stop after 3.
U know u want this, everyone at lastsparrowtattoo knows u want this, time to make the jump :)
