Hard to say on the taller castle part because of the wardrobe in front of it, the left side definitely looks like a ground row in from of the backdrop to me, there's definitely a little bit of light leak under set of double towers right in the middle of the low towers. Part of gradient though is that its lit from both the top and the floor. But that could also just be a rear projected silhouette and the cyc "lighting" is part of the projection.
