Sculpting Mountains from foam panels (Forced Perspective distant range for O-scale)

The O-scale Roundhouse is coming along. Those aluminum panels are sharp, I should have worn gloves. I used power grab adhesive caulking to adhere the panels to the plastic model super structure and then used clamps to press them flat as they dry, otherwise, they tended to pop out. These photos show the roof almost complete, but a row of roofing panels are not glued down yet. Weathering and "glass" for the windows are next.
