Flat colour
I used a wide variety of colours with the idea of making it feel exotic and fantastical.I think the lighting and shading will tie everything together at the next stage.
After some experimenting, I landed on this composition. I am fond of using portrait format for environment and landscape images and I think it worked well for this image too. By placing my character at the bottom and having the worlds build on top and inward,i feel like it gives an good sense of scope.
