The story is evolving. These are concepts for a personal concept art project I've been working on, I talk a bit more about it in some previous posts. Here and here.
Initially these aliens were going to be pretty scary, like jailers, but the more I'm developing the story, I'm actually moving toward them being more like stern teachers. They are teaching their experiment subjects to use psychic powers. The subjects are not aware that they're subjects though. They've been brainwashed since birth to believe that they are training for a great cause, to save "their" planet. Truthfully, the entire experiment is to assess the psychic potential of several "lower beings" with the goal of once they've found a good fit, to invade that races planet and use all the inhabitants for slave labor.
These were my first real explorations of the aliens. When developing something like this I typically like to do a first pass on everything before I start to put a lot of time and energy into some more finished pieces. Basically I see it like I'm creating my set of toys, that once finished I'll really be able to play with without worrying about what things are supposed to look like.
Here's a few other quick doodles made in the process.
Hope you guys are enjoying the process. let me know what you think in the comments! Thanks for looking!
