I like the backstory you've come up with, and it looks like you've come pretty far with your sketches and ideation phase.
In the last sketch for the final image I think you maybe could get a little closer to the mining tower and the city around it. Right now a lot of space is dedicated to pretty much nothing but clouds. Other than that, just keep on pushing!
i was really further with it
a lot of work ahead ^^
Sorry for the bad hiccup with your file! I'm glad to see that you recovered from it, and I'm loving the progress. Keep it up!
thanks. will do my best to finish it ^^
Oh man... that is a bad luck... Good to see that you've overcome this and keep doing the great work!

Aw yeah really nice man! Love the comp and design!
I'm sure it's your next step, but adding some ligth and dark areas to work on the atmosphere and lead the eye would definitly give a boost
