Very nice. Rail revolve is a nifty feature. One hint about converting nurbs to mesh in Rhino; Rhino loves that critical angle for deciding where to place polygons on a mesh. That's why you have the straight long polys on the bud vase neck. Sometimes this can be a bear when you want to smooth. Choose the detailed controls when converting. Set the default aspect ratio of 7/1 to 2/1 or 1/1. Change the minimum angle to 45. Set the Min initial grid quads to a higher value 64, 96, 128... You can get some neat cut glass shapes just by how you allow Rhino to resolve the mesh. Welcome to the world of insane poly counts;)
