Barney, this appears to only be a non-surface structure. I believe they intend to make the coloring and more fine details on top of this layer, am I correct ryan? At least, that's how I go about building things (make a foundation and base structure, then build on that ).
basically its the outer structure but well be making it look better once the main structure is built so sorta what dunsjohn said im hoping it will look a lot better anyways
