After going a bit of the theme in the third sketch, I decided do something more obvious when drawing an oasis. A desert like place around, and the character is lying down in this green oasis, chilling and playing with the creatures there. I also brought the robots from the 4th image, and it worked really well with this weird rounded office/house to make a good mix of futuristic roots. I'm still finishing up a 5th sketch in which I'll try to mix what worked in these four, but for now this image seems the strongest to me. Although sketch 1 is still a good possibility
