This is Horim's "Night Market Galaxy." This small version doesn't do it justice, so be sure to view the larger original.
It's a market butcher shop and eatery. Maybe it's not the most pleasant diner in the galaxy. It certainly isn't the cleanest. But you can't beat the fresh facehugger. And I see that they've got human on special. Yummy!
What's that reptillian-looking creature on the far left? A Gorn?
