I found two small space-themed builds on Flickr today that I really liked. The first one, by IamKritch, reminded me a lot of my own building style in my recent abstract MOCs, using SNOT to create a smooth brick-built base. It depicts a pair of Classic Spacemen encountering, of all things, a dirty sock:
The second build is this deceptively simple scene from O0ger entitled "Maintenance":
There's some fairly complex greebling going on in the opened wall section, and it offsets really nicely with those big smooth panels. I also like the choice of colors for a very muted photograph.
