It seems as it is the future where Dragons apparently live or have been created, it also seems as this one is hiding and protecting the orb, maybe something Humans use for a power source? and it belongs to Dragons?

Overall the image is really good, I like the concept and how the viewers can image the plot of the image, I'll give it a solid 5/5, it deserves such rating.
And I especially like the colour of the wings, although... if they would be stretched, they would look even more amazing.

everything about this is good. details and things like the unfocused branches in front to the buildings behind the stones show your strength as an artist. good work!
also, shiny shiny :3
