Alright, I've finally got all the low-res textures remade and worked out the colors/lighting. There is still a couple brush errors for those that look closely, but for the most part this is what I plan the alien base to look like.
If anyone has any comments/feedback/suggestions now is the best time to make them. I'll start building the other rooms using this style and the more that is built the less willing I will be to make a change.
