Hi there! Cool environment! I think the best way to push this further is to take another look at the cast and form shadows created by the 3D forms. You’re already doing this nicely on the cylinder of the tower, but the buildings below feel a little flat when you focus on the larger value shapes. Try increasing the contrast between the light and shadow sides of the forms so the volumes read more clearly. I did a quick paintover to show what I mean, hope it helps! | Artwod Feedback
