Reading the face, planes and composition before touching the machine.

Clean stencil and a palette of diluted blacks ready for every layer.

First tonal structure on the skin so it heals evenly.

Eye-nose-mouth: the likeness is built here, before any detail goes in.

Volume through layers of diluted black, dark to light, no oversaturation.

Highlights and final detail. The touch that separates without covering.

He clearly explains how to adapt complex designs to very small sizes without losing definition or durability. The part on color, saturation and needle choice especially stands out, with practical tips you can apply from the very first moment.

A beast with the machine, he explains calmly and takes his time. I wish I had the money to buy every masterclass, because I'm opening a tattoo studio and it would come in really handy. A beast, seriously. I hope I get to meet you in person one day.
