Pen is similar to tattoo inking in some ways I guess?

It is by the fact that you can't erease anything and it's free handed. The problem with the tablet is that you've a lot of help provide by the program ( you can zoom, some brushes correct your lineart so it look less shaky, you can make perfect line or circle and of course erease or get some step back ). What's important here is to train to get better without all of those thing that I won't get once I'll have a tattoo machine. Because it will be way more complicated with all the shakes from it and if I'm not even able to be good on paper, there no way I'll be in real situation.

Sorry for the long explain x)

No that's fine! I have a few tattoos myself so I was curious. Makes sense. :)

thats beautiful
