Well, in my experience, even if you are looking at a stained glass window from the inside on the sunniest of days there's still a muted quality to it. I mean, the end result is filtered natural light... In a lot of art I see that tries to replicate the stained glass effect, the artists tend to go too bright/brilliant with the color and it just doesn't capture the mood in the same way. You, on the other hand, whether intentionally or not, have and I think it's wonderful.
Whoops, forgot the font credits! It's "Diogenes", by Apostrophic Labs on Dafont.com, link here: [link] and it's the same font used for the upper line.
I'm not sure if I'll do a series or not, yet. I've considered it, but it's more likely I'll end up doing a host of rune-related drawings. I know I've been playing around with something that has Raidho, and Thurisaz was part of the centrepiece of "The Wheels of Hrothvitnir's Whelps".
