As far as criticism he actually showed me how I can make better lines and said that it wasnt good I never thought it was and I agree with the inverted thing ima use thatMark @TexasPT is right man. Believe me he is just trying to help you out. So I am interested to hear exactly what your mentor is telling you about your practice piece?
I said go smaller it is easier to concentrate on getting everything right. I still stay behind that statement, but do big tattoos as practice nothing wrong with that. Just slow down and maybe not finish it in 4hrs. You are rushing, if your mentor thinks that is good training I think he is mistaken.
BTW, Mark the inverted colors is awesome, nice pointer.
Yeah I've also started using a heavier machine to reduce some wobble I think I used a 3 for the first and maybe a 5 on the dragon but that was trying different things and that dot in the middle is from bad choices on where to end a line and messing it up on the reconnectTry a bigger needle grouping, pulling long lines with a small grouping will show every wobble for sure. To build a bit of confidence and some 'getting used to', I'd go with a bigger grouping like a 7RL.
