Hello everyone I have a tattoo which i have had for around 10 years. I have a few issues with it. The edges are not as clean as I would like and also the fading is really faded and skin tone showing in places. Also I got a really deep cut across it which didnt heal. I want to go back and have it all re done only issue I see is the thickest parts are around 25mm thick so I dont want the touch up to make it look too thick. And suggestions on changing the design or ideas on touch up work thank you see pic below.
