I recently did a poster design for merch of an upcoming BNHA fanzine and needed some profile blancs as layout elements.
Profiles certainly tend to be my favorite kind of angle on a face when it comes to shapes and shading. It's certainly one of the easiest there is, but it's a great test in pin pointing specific characteristica of a face and exercising shading techniques.
While these ended up being pretty heavily edited losing most of their color and shade for the actual poster piece, it's still helpful to have a fully rendered and colored version to edit since it leaves open more options to play around with.
Once I get clearance I'll be sharing the poster design as well, so be on the lookout for that :)
