Here's something you might be interested in: I'm planning on throwing together a super detailed, epic as hell 40K painting in the near future. Not sure who'll be in it yet; most likely either the Dark Angels fighting Tyranids/Eldar or Chaos taking on the Imperial Guard... Stay tuned!
A sketchy painting?! This is amazing! You're so good at blending colors and shapes. It's like, when you look up close, you can see it's sorta messy, but take a step back, and it all comes together in this fluid kind of... impressionistic representation of reality, I suppose. I do admire that. I really like this painting.
I think a lot of concept work takes on an impressionist air to an extent; the illusion of detail is really the goal when you have tight deadlines to work to. I envy the guys who can really pull it off - glad to hear you think I'm getting there!
