I'm using parts from assets I've purchased from Poser model stores. I've purchased the rights to the Grey alien and Raptor alien (used to represent the reptilians) for my Invaded project from before. Just reusing them here. Same universe, different game.

I have however done some filter and effects work in Photoshop to tweaking colouring and lighting and such. The backgrounds are from free domain images I've found on the net.

Actually one of the aliens, you haven't seem them yet, I manually generated using different filters and effects. I think they turned out pretty good. Hopefully I'll have their description written and I can post them as well.
