Here are some technique tidbits:
The torso is built around the main gun and the structure needed to extend it.
This was a very fun part to design. The gun is mounted on a backing which is two
bricks thick. Little 1x2 slider tabs extend horizontally from this into a row of
1x4 recessed track bricks in the chest cavity. It slides smoothly, yet keeps the
gun perfectly stable even when fully extended. I've never used those track
bricks and sliders before (for their intended purpose).
The flip down front panel is a good work platform for gun maintenance (including
safety railings). Also it gives a hint of how the curved upper chest was
constructed, click hinge bricks wrapped around an inner technic frame. You can
make a perfect semicircle with the hinges that have fingers on both ends. They
become like a curved beam that you can then attach plates to.
The guns in the back pods are on "disappearing gun mounts" that lock in place
with elastic bands. I designed them after old coastal defense cannons that would
retract behind a fortress wall in this fashion after firing.
The head/face is built on a vertical corner turned 45 degrees rather then a flat
plane. I've never done that before. This opens up new design possibilities (for
making malevolent robot faces).
The forearms and sholders are given roundness with SNOT applied slopes. I tried
plates at first to reduce mass, but the compound slopes were smoother looking.
The lower legs are sort of built like a dirigible, or a skyscraper. There's a
technic frame with a skin of plates wrapped around them, connected to each other
by hinge plates. A minifig can enter in the door at the back of the foot and
climb up into the hollow leg, if so inclined. There was so much empty volume in
the legs that I turned them into bomb bays filled with racks of M.O.A.Bs
(massive ordnance air burst bombs) for the robot to drop when flying.
Plate contouring is courtesy of a zillion small wedge plates. Gone are the days
when you could only use big wing plates. The small ones give a lot of
flexibility, but you need a zillion of them. (Oh no! They only make them in the
"New" grey now!)
Each shoulder joint uses dual turntables for strength. The lower arms have such
a high sloped brick content that they were too massive for anything less. The
hip joints also use a similar design.
The waist doesn't have a turntable to twist, unlike the Gundams. The torso was
too heavy. The tilt of the waist is controlled by dual worm screws acting on
large gears (which can be seen at the bottom of the gun cavity). This reduces
slop when tilt is adjusted to compensate for extending the gun or moving the
arms forward.
The ankle joints are built up technic structures rather than throwbot gearboxes.
Again mass dictated a stronger design. (I further evolved this ankle for a new
Gundam which seems immune to being knocked over, despite being prodded.)
Articulation and poses? Well it has worm gears in all the joints but it's really
only safe to pose the arms, or it will keel over like a torpedoed battleship.
The back pods make it very top heavy.
Also I included a lighting element for the first time. There's a Lego light
brick with a red lens embedded inside the head to make the robot's eye slit glow
with brooding cybernetic menace.

p.s. I know you want to see the big gun fire. Kaboom! Yes you do. I'm working on
a photoshop. I learned some new graphics techniques too.

It was all about rounded shapes and gigantic concealed weapons - so giant that it looks like they couldn't possibly (...) (20 years ago, 3-Jan-05, to lugnet.build.mecha) !!
