Hey all-

This is a render of my latest, a battleship meant to complement the hunter/killer from previous posts called Avenger. It's bigger and much heavier, with no hangers but more guns and torpedo batteries. I have all kinds of in-story reasons for why things are the way they are, so if you wonder why I did something in particular feel free to ask! I actually sort of enjoy how picky the guys get with Star Trek ships, and designed mine from the inside out to try and stay as realistic as possible (for an imaginary spaceship, of course...)
I found a great tutorial here on how to make a planet for the background. I only had two brushes that worked for clouds and I was running up against a long trip for work, so rather than get the planet right I cranked out a couple renders and away I went.
All work done with Sketchup, Twilight Render, and Photoshop.
So, other than the clouds not looking right, any thoughts?

Thanks!
Ryan
