I haven't used AC3D, but I did take a quick look at their site this morning. It is a subD modeller I noticed. I suspect that this model is the base cage with no subdivisions. If you wish, post a larger wireframe and a clay render if possible. Plus, a couple of reference pics or links to them. I guess this is anachronistic using architectural details from sites like Knossos? With that as a start we can rip it apart and show some techniques and pitfalls to avoid.
