The ball is a simple mass productive Mobile Suit that lacks the more
humanoid shape of the advanced Suits. My first version of this model has
appeard in the background of other pictures but I recently rebuilt the
model, almost from scratch, so I decided to do a picture featuring the
new, high detail model. The colony cylinders in the background are built
to the same scale as the foreground models, I haven't used forced
perspective here, the colonies are absolutely huge (30Km long) and placed
a very long way behind the other models.
The space backdrop was done in a program called Universe which I
downloaded recently, its just the job for generating space scenes, with
options to add starfields, star clusters, close stars, nebulas and gas
clouds.
