awesome first attempt mate, I just have one suggestion, you might want to put them on a share site, put them in a folder and upload it, would make it easier to read and download, but that's up to you.
Wow. It reminds me old games, like http://www.gamerankings.com/pc/339961-aliens-versus-predator-2/images.html
Thanks. I also like my sci-fi games- Halo series, avp, resistance 2, crysis, half life and aliens: colonial marines then combine all this for a story idea. So many ideas to create.
