Developing Proportion Principle in Sketch-Up

I am now getting towards the end of the project so I have begun to develop my design principles further using Sketch-Up. I feel that at this stage they are quite basic and not as technical as I would like them to be.

The following are some screen-shots of different angles as I develop my Proportion principle:

The development I have done to this model is very quite simple, due to the fact that I am quite happy with it as it is. All I have changed to it from the previous proportion developments is firstly duplicating to create more of my boxes, and secondly changing the orientations so that it the 'poles' are going along every axis. This is very simple, yet I find it quite effective, both aesthetically but more importantly to express my proportion principle model.

Top View. Proportion is clear through the different scales of the boxes, and the different lengths of the 'poles'. The shadows that are on the ground help to emphasise this idea as well.
