Planet Krikkit from the Hitchiker's Guide

A first bit for an incoming project I'm working on :). This is the planet Krikkit from the third book of "The Hitchhikers Guide to the Galaxy" : "The life, the universe and everything". This planet is dominated by an enormous spaceborne computer "Hactar" created to invent the ultimate weapon of destruction (which is a very very tiny ball/bomb). Anyway, the history of this fictional planet is HUGE :) so if you are interested and want a good laugh : http://en.wikipedia.org/wiki/Krikkit#Krikkit

I want to add some texture, but I'm not 100% sure :) You can see more in attachment.
