Hello! I present the last diorama do with this design (at least for a while!) We must continue to explore designs!
As above was used a base of Styrofoam, I will apply a foam plate to the floor and the wall. The roof and the structure supporting the portal, are Polyfer, like the same portal. I recommend using this material to achieve carve presicion, and gives a finish that looks great. As the colors, use as a base and cobalt blue to light blue lagoon edges with dry brush technique. The brand was using paint EUREKA. For columns, use four 40mm PVC tubes, the bush in microindented cardboard, and add as a ribbon detail very thin rubber eva spiral.

I hope you enjoy this diorama, until next time!
