Nice new sigs
capture. The blending of the background is eye-catching but, because the colour is a bit saturated (or maybe too bright) and similar to the render that it makes the render a bit flat, you know? Blends too well into the background.
I really like your current sig 'Evangeline'. Colour balance and depth is really nice in that one.
LOL, I see that you're also experimenting with lighting. I'm working on getting that down myself.
