Giant Girl?
The atmosphere of this is pretty good and the balance is alright. The color work looks good too.
My beef with this is mostly the placement of the character to the rest of the world.
You should have her lower on the canvas and a bit larger to give the impression of her setting close to the viewer.
At the moment she looks like she is a giant girl setting on a ruin rather than a just a normal girl setting on a small pillar.
You could have also gotten a little more dramatic with the clouds in the sky.
