My second tattoo

You need to do lines in one clean sweep, always make sure your machine is moving forward or from side to side. It looks like your either not doing one pass lines or not stretching the skin taught enough. Maybe even a combination of both. What voltage are you running your machine at to line?

Ouch. YOur line work leaves much to be desired. please get your line work down on paper before ever touching a machine. Not to be harsh, but man you need to learn alot of what a good tattoo is. I strive to learn and perfect everyday. Good luck, work hard and follow your dreams. the key is the work put in and effort to be the best.

Oh wow, 10v is very high, especially if you’re new at the trade. I’d suggest learning how to tune your machine better. I tuned my liner so it’s hard-hitting and I only run it at 7.6v I’d suggest not doing multiple passes on the same line UNLESS you let it heal and then do pass over it again. But that’s my opinion, and if you’re going to do multiple passes in one session make sure you can see your needle and hit on the first line you made. If you have great fundamental knowledge of technique and machine tuning it shouldn’t matter if it’s your second on human skin. I’m not saying it should be fantastic but you definitely should have cleaner line work. I’d also suggest getting pig skin and practicing on that, it’s very close to human skin and you’ll be able to get a better understanding of how to line on human skin. Not trying to discourage you just giving advise SHOULD HELP you as long as you do it.
