Epic Reaver Titan

There's a lot of hype going on for the upcoming new edition of Adeptus Titanicus (and it looks great!) so I gathered up the motivation to finish this Reaver I've been working on. I had to take the pic outside to get the colour on that base right.

I did the blue carapace with my airbrush. I'm having difficulties keeping a consistent stream of paint going, it tends to clog up no matter how clean I keep the brush or how much I thin the paint. The result is ok, but using the airbrush is really frustrating right now.
