Update: Putting all these friendly creatures together, as there was no point in keeping them in separate posts.
Alien guy - Just a harmless little alien. It's a cheerful and social fella, eager to give you a hug, but I'm afraid his arms (all four of them) are so short that he can barely wrap them around himself, so no hugs to be given.
Drago - I think that one of the heads is feeling quite done with their life, or at least seems a bit overwhelmed with the other one's attitude.
Pug - it's not a pug, of course not. Just a vicious alien creature!
Astronaut - The wonders this guy may see, traveling the space all alone! The companions he might gather...! The strange fellas might he meet!
Hope you'll like these concepts! Have safe travels, in space or otherwise.
