Seems like a dangerous place to sleep on.
I like the sky. It is very well made. The bright pink colour has a nice contrast to the blue.
I feel like it could have a little more datail. Maybe something more on the cliff in the foreground. Oh well.
It looks like the sleeper has an astronaut suit on. It gives the idea that it could be outside earth. The bright dots above the cliff tops also add to that, as well as the emptyness.
