Quick space ship concept

I had "business" correspondence last night (I'm living by L.A. time now) and I did this concept. First qucik sketch (idea and shape) was made in 1 hour, but I've decided to finish it in exchange for my sleep. Total time was spent 4 hours.
[it is bif transport ship designed to resettle latinos, russian to far planets :) kind of colonization]
