These were a batch of super fast silhouette thumbnails I did as an idea generation exercise. The top two were done with the general idea idea of space ships or sci-fi structures. The bottom set was done with a brush I created in Photoshop to quickly dump out a bunch of "sci fi widgets" These could become structures, weapons, vehicles, equipment/console stations, etc. It's really meant as a page of starter ideas. I plan on taking some of the space ships up to a higher level of polish, perhaps incorporating them into an illustration, or presenting it as a piece of "concept art," same with the "widgets." I figure it might be fun to do a sci fi outpost amongst a landscape with one or more of the shapes.
