Mass, The Final Frontier...

They say, in Mass, no-one can hear you scream......
Sorry, Im a sci-fi freak, and couldnt resist mucking about with this night shot of Baltinglass Church.
Never messed with PS before, and probably never will again.
Leave it to the desk-jockeys, I say.
Now, wheres my light-sabre....
OK, now I need advice. I was trying to make this look like a Battle Cruiser, or some menacing Starcraft.
Where did I go wrong?
Constructive criticism appreciated.
