Martian Ships Concepts

I have a couple of preliminary tasks that I set for myself before I actually go ahead and start the final illustration for the Art Order "Princess of Mars" challenge.  The first task is to design a Martian ship.  I must admit I'm really awful at vehicle designs.  Prior to these sketches I did do a few sketches of sailing ships like galleons and even modern ships like destroyers just to get a better idea of the basic shapes and silhouettes of ships.  I even had a look at one of Feng Zhu's free tutorials on vehicle design to try to get my head in the right space, but I just ended up being depressed at how dull my designs are.  As with most things it'll just take me time and a LOT of vehicle concepts to really get better at this.

I think I'm going with ship number 3 just because it looks the least Earth-like.  Next up, I'll have a crack at designing what the green men of Mars look like!
