Hi!
I've just uploaded in the post below the first tutorial about painting Zarshia Bittersoul.
An airbrush is not required for this tutorial, but I did used it for painting the white, and later fluorescent green color on the magic flames. I could do the same with a brush, but it would simply take more time. I think you can clearly see on the photos that using this had no impact on the model at all, and all of the OSL effects are hand painted.
I hope you like it so far!
Regards
