This is a model I've been working on for some time now, and I plan on it being one of my better portfolio pieces (when I put a portfolio together). It's a steam-powered tank inspired by older model British tanks and the ones from Warhammer 40K. This animation peels back the various layers of the vehicle, showing it's guts in all their glory.

First Layer: The tank itself, with it's dual-turret setup. The boiler and condenser assembly protrude from the back of the tank, leaving them rather exposed and vulnerable. These tanks were used for long-range support, and those engaged in close combat would have increased armor around this area. The secondary commander's turret on top of the main one houses an antipersonnel and antiaircraft dual-cannon setup, capable of defeating most lightly armored targets with ease.

Second Layer: With the turrets removed, you can see into the body of the tank, where primary ammo storage is situated. You can also see the pivots that power the rotation of the main turret.

Third Layer: With the top armor and side plating peeled back, you can now see the water tanks within the track assemblies, as well as most of the vehicle's powertrain. Both tracks are powered by a pair of steam pistons which rotate a large flywheel containing a simple transmission to engage or disengage power. The flywheel-gear is connected to the drive wheel via a heavy chain, providing immediate and reliable power.

You can also see the firewall which separates the main cabin and the boiler compartment.

Fourth Layer: With the tracks, hull and firewall removed, the wheels and casters are visible, along with the forward brake assemblies used for braking and steering. Control apparatus' are visible behind them, as well as a pressure distribution control box just before the boiler itself.

Fifth Layer: With the side armor and floor removed, you can now see the underlying structure of the tank's hull, along with the catalytic fuel tanks. Stored in two parts, when the fuel is mixed and compressed significantly, it combusts and creates a substantial amount of heat. This in turn boils water within the boiler, creating steam to power the vehicle.

Sixth Layer: This final layer shows the main fuel and reactant tanks, as well as the two water tanks and boiler assembly itself.

I plan on modeling the interior of the boiler and adding a ton more detail as well, since since I was a child I've always been fascinated by steam power, as inspired by my dad's fully-functional model steam engines. The driver's area and interior of the turret will be fully modeled as well, so don't worry about that.

Please provide me with any and all constructive feedback on this model, it's definitely one of my babies and I want it to turn out as awesome as possible.
