Beautiful stuff as always, Adarias. Your colour choice is always an inspiration. that said, while I respect your vision, I have to agree with Pawige. The first thing that struck me when I saw the coloured ones was how busy/confusing they look (at first accentuated by the light BG, but nonetheless...) I think, maybe through a bit of palette tweaking, you could soften these a bit, make them less confusing, without losing to much by way of detail/style.
Then again, this is probably a personal taste thing on my side, and as you're the artist, the importance of your personal taste far outweighs my own as far as your own work is concerned. They're lovely regardless.
