Gotta love silhouette artistry, with layers that fade in the distance... reminds me of some old game I played as a kid, Journeyman, maybe?
Feels like it might've looked even better with all natural scenery, as the bridges and buildings come across a little wonky in form, not as grand as you'd imagine an ancient civilization.
Really cool with those layers and shades though. Would be interesting to see more like this.
