This is a recent commission I finished up from a returning customer of mine. He's an awesome guy!
Anyway, this was inspired and is my take of Corvus's Fortress Maximus.
Client wanted the "same thing" so I took C Metroplex, and put my spin on the project. The ramps are retractable, and the tower opens up to expose the "docking bay" for planes to land on. There's lots of little cool features on this custom, like the LED laser light that's a lamp post in city mode, but attached to the city mode's crane and forms a giant kick ass gun for the robot mode.
I also painted up 5 minicons, these guys were a paint to transform and detail. tiny tiny brush did the trick. I will have more pics on my site very soon, including close ups of the minicon robot modes.
