update: finished! pics in post #22. Here's my wip drawbridge. It's 20' including base, and is made of Styrofoam. The details, which I'm working on now, will be made from various materials. This is my first diorama, if that's what you'd call it, and my first time working with Styrofoam in general. I'm waiting to borrow a heat wire (?) to smooth out the edges of the door. All the lines were drawn in and then carved out using a drimil. This is just a mock up of the size for the pieces and crest, not what will be used material wise. I'm going to sculpt the crest, unless someone has any better and easier ideas. I also don't know what to sculpt it out of. I would like it to say light in weight. So far my options are model magic and air dry clay. I am open to any and all suggestions. Thanks!
