zBrush takes skill & talent but it's still 99.9% faster ,easier ,cheaper than real world sculpting.
Don't even half to worry about the humidity.
Same for Photoshop.

I don't do any Art in the real world any more.
Don't even have a real world studio any more.
Some times I miss doing real world Art.
But I'm sticking with CGI.
