AB,
This is some incredible work! I'd definitely suggest putting a portfolio of some kind together to highlight your work in one place. Whether it be a professional site, deviant art, a wordpress, tumblr, or a blog, a place to have your art centrally displayed is extremely helpful for finding work. I just have a [url]blog:
http://www.swhowardillustration.blogspot.com[/url] or
http://www.stevenwhowardart.blogspot.com, but it has allowed me to land a couple freelance jobs, my now full-time job, and many others asking for my art that I've had to turn down or pass on to others. Your work is amazing and I'm sure that, even if you already have gotten work, many more will want to hire you with a central site for your work. Just some food for thought. I look forward to seeing more of your work, especially now that I have been getting into the 3D modeling. I really dig the stylistic approach to the renders. Do you have an image showing just the polygons of the Apollo stuff?
