Developing Datum 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 Datum principle:

So the main thing that I have done with this model in terms of my progression and ongoing development is learning how to create spheres in Sketch-Up. I felt that this was a necessity following drawing onto my print-out earlier in the project. By now incorporating spheres it increases the overall aesthetic appeal and professionalism of my model hugely.

Top View of my model. The shadows on the ground help to really emphasise the scale of a few of the spheres. 

Side-view showing the differences on the y-axis. By having the spheres on different heights on the y-axis it helps to create a playfulness within the model as they can be seen as 'floating' instead of if they were all at the same height it could create a sense of structure and rigidity within the model. 

Another side-view helping to emphasise both scale and placement within my datum model. 

This perspective view helps to reinforce the datum principle within the model as it was not very clear from the other screenshot angles.

My development of the previous model was to duplicate around a large central sphere as if they were revolving around it (which was my idea behind this model). 

A front view showing the different heights of the different spheres. Also the scale of the central sphere creates a strong focal point for the model which is what I wanted within this development.

Another perspective view, again bringing emphasis on the large central sphere in which all of the little spheres are revolving around. Almost like an asteroid belt around a planet for example. 

Close up perspective view in order to bring attention to my datum pattern that I have put onto each of my spheres. I have changed the height and width values in which it duplicates a pattern for a face in order to make my pattern more zoomed out and thus being able to appreciate it more.

One last perspective view with shadows on.
