The way my other dragon is laid out and how it is done, it wouldn't be able to really 'mesh' unless I filled a lot of void space on my back first with that pattern. But it's alright! I'll get it all balanced out. I have an idea for some fantasy-style runes I want to get down the back of my neck, so that might help a bit.
You can see how wide the gap is between my left shoulder and my right shoulder. So if I got a tattoo on the left the same size, there would still be a huge gap. Which, I like. I don't want my entire back covered.
So it's a balancing game.
That's why I find it ambitious when people like you guys want full back tattoos! It's impressive when it's done well, and something I can never do. So definitely keep this thread going, haha. I love hearing about everyone's plans and whatnot.
