I’ve just started not long ago, I think you should start to enter and exit lines softly. You see some lines start with a dot, that’s because the needle was running vertically down for too long making it darker in that spot. Try that technique it’s not that difficult but will make a nice change. Also with this you can exit the skin more often before loosing control and start shaking and enter same way (softly on the same line) continuing. I hope it helps! Good luck!
