Here is my go at the weekly challenge, Im just glad to finally have submitted SOMETHING but decided to submit early because i don't want this taking up my school time. 

Only thing i am dissapointed in this is that there are clearly two different styles showing (The machine and skeleton) which shows how bad i am as a technical artist, but eh... whatever...

too many transperencies used but here are the basic colors.
