Okay  zanian here's a rough for the 8x11 image I'm working on.

I had to modify the uniform a bit as your characters anatomy is a bit different from a humans (like higher shoulder cover/pad/things) and your alien hips show up strangely under clothing too. I also opted not to give you a gun as that would defeat the purpose of having you use those nasty claws, teeth and acid blood eating through the floor underneath and all that good xenomorphian goodness you'd get from hand to hand combat. Your tail sort of circles around there in back.

The commander fellow will be a ghost in the background, ordering you on, his ghost cigar smoke will appear to be real though as it covers the background. I'm thinking generic xenomorph ribbed walls or somthing for that.

If this looks good I'll go on to ink!
