I've referenced this work of yours in an interactive story (RP) that I'm hosting for some friends! Apologies for doing so without your prior permission, but the design was just too perfect! He's only been mentioned once, as a member of the "Vanguard's Finest". If you'd like me to remove the hyperlink, then I will do so without hesitation.
Hmm its hard to say as I tend to change the colors a lot during the process. But i like to work with warm colors and a lot of greys. What's important for me is to have a base temperature for a painting (may it be cold then i go with bluish colors and add all the other layers of color to it. Anyway its weird, I cant really explain this as i'm very impulsive when it comes to color and experiment a lot before choosing a certain color. But if you want to get more into that subject. This blog is relly awesome when it comes to light and colors and what can be achived with it: gurneyjourney.blogspot.de/
