Astronaut's journey

I didn't upload a lot lately, so I'll drop some older works.

YES I KNOW I WROTE WRONG YEAR ON ONE OF THE PICS. I KNOW.
Anyway, at one point I was drawing nothing but astronauts, looking for something, exploring galaxy, discovering.
Was experimenting a lot then, and these two finished illustrations are the outcome. I really like how they turned out!
