I felt like working a bit more on alien-ish starships. So here is a transport (actually some sort of Tug craft / pusher, freighting a container that can detach)
I'm particularly happy about the engines on this one as well as the curving of the container.
Viewing Large / on Black is recommened for more detail
Edit: I replaced the photo with a slightly different presentation that more clearly depicts the general shape of the ship
Edit: Photo replaced again to better balance things out in the presentation
