Killzone Inspired Sketches

Whenever I do character speedpaints I often end up with a bunch of Helghasts. For some reason the character designs from Killzone stick with me. Must be those glowing eyes or it's just a part of Dutch pride. Anyway, I thought it was time to do some proper Killzone inspired sketches to get it out of my system.
I went for a desert setting with these ones, mainly since it hasn't been featured in the games yet. However, I did want them to be more heavily armored, so I guess they're sporting climate-control in those suits. The desert setting kinda went out of the window along the line although some features may be reminiscent of it. I really enjoyed doing these and I think I might do a couple more in the near future. Of course this is by no means a job application...(or is it?!)
