Can't help you with any other modelling sites specifically, but feel free to post here! Under the main headings of "On the workbench" and "Under glass", there is a category of "All the rest" for your works in progress and finished builds, respectively. There, people post a wide variety of subjects,styles, and media that don't fit the "model cars" groove, but are still interesting to some of us. Modelers learn from modelers, regardless of subject and medium. Welcome to the forum!
