First off: 'Bout the colors, I wanted to make a whole light grey marathon, as you can see, i started on the front half, it's light grey.
But besides the color. It's the BIGGEST, most ENORMOUS thing i ever posted (or made).
That barely looks like ANY ship from halo. It looks more like some large, deformed brick made of legos. This is the problem with legos: the results never look like the actual thing, because you're building the "model" out of arbitrarily shaped pieces of plastic.
