Hi Marco,

GREAT tutorial. Thanks. I was able to follow along and replicate quickly. I'll keep that in mind.
I tried a Wacom years ago and it didn't suit me. I prefer a direct drawing approach at this time (and I do so on my iPad Pro with Pencil). Thanks though for the suggestion.

Yes, I did see the glass textures from this same link you sent previously. I wonder how they do it? Any ideas?
