Developing my Sketch-Up 3D Models

Following my drawings on my 3D model print-outs, I have begun to go back into Sketch-Up and develop my 3D models further. 

I have used some of my ideas from my drawings and others I have just experimented with using my original 3D model as a basis. The following are where I am at: 

*The models that are not picture here - Datum, Symmetry and Rhythm have not been developed enough to show progress at this stage.
