Oh, thank you! This is a nice surprise. :D
I do not use masks, mostly because I've never been able to figure out how they work. I use Krita at the moment. Masks seem like they do similar things to the "Inherit Alpha" and "Alpha Lock" options to the right of every layer, which I use constantly. If that's not quite the case, it'd be awesome to figure out how they actually work. They have perplexed me for a very long time hahaha.
Hm, that's true.... I've not thought to use that method for much outside of shading, but it might actually be really helpful with that dragon. In Krita I can use blending modes to create the same effect, as greyscale is one of the options alongside colorize and the like.
Thank you again! I really appreciate it. ^^
