Hi everyone. I had a series of butterfly tattoos about 4 years ago, they go all up my leg. At first they looked good, but now it's like all the detail has gone and they look more like blobs. Also an arm tattoo, which I think could look better if touched up. I will try to attach pics. Can anything be done to sharpen these up? And if so, how on earth do I pick someone trustworthy? For obvious reasons there's no way I want to go back to the original guy who did these. I'm near Dunfermline in Scotland.
