Hi!
I've just uploaded on my patreon a step-by-step PDF tutorial about painting Szarekh's cloak (It is in the the post below).
The idea for the cloak is to make it look like it is not entirely here, its moving and slowly materializing and dematerializing in many places. The idea is to create this effect with the concave and convex pixels.
Even though the miniature is custom made, there is no reason why you wouldn't try out this effect on your own miniatures!
I hope you like it.
Regards
