By far the best online course, no contest: nobody explains like Charly. He has an incredible level of knowledge and explains it in a simple, direct way. I recommend it 1000%.

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.
