Thermopylae

This is a character I've been toying around with and bouncing off of Phoenix. The only thing close to a name I've got for him is the callsign 'the Spartan,' so, thus, Thermopylae.
The one thing that I'm worried about this picture (well, the most major one) is that the Xenodragon might look like he's attacking or sneaking up on the guy, which is not my intention at all. Its kinda hard to signify a Xenomorph's direction of attention since it hasn't go any eyes to do so. Its head is down and mouth snarled in aggressiveness, not because he's looking down at the gun (which took me FOREVER to draw over and over again until i got it perfect, but in the end just gave up) and the claws are now raised in pretense to swat at his head. Meh. I finish this in a day, give me some credit. I want to make this so much better, but I don't know how.
One more thing, this one is really detailed and if I made the images any smaller, you wouldn't be able to see anything minute, like the Spartan's face, which I worked long and hard on. So the images might be a tad on the large side. It can't be helped, but just a heads up.
I'll continue working on this again and again in the near future.
