I'm all for tattoos and I even appreciate game tattoos, but I'm not a fan of this one. Just a matter of style preference. This is too dense and colorful for my taste. Kudos to the artist though, I think he did the best job possible of adapting this picture to a tattoo-able design.
looks like it's very fresh, that could be the reason for being a bit bruised. i got a small one (not Diablo styled) this summer and even so it bruised a bit at first. don't forget that after the tattoo is made you really got a wound there from the needles and the colors go to the lower layers of the skin (black is not as deep).
i plan to make a Diablo styled tattoo on my back when i can afford it, but it should be a good while till then. the design on this one looks pretty good, i have to admit.
