Developing Symmetry 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 Symmetry principle:

Front View of the first step in my development of my symmetry model. I have duplicated my original model and mirrored it on both axis. 

Perspective View of the first step in my development of my symmetry model. I have duplicated my original model and mirrored it on both axis.  

Top View of the first step in my development of my symmetry model. I have duplicated my original model and mirrored it on both axis.  

Using the developed model above, I have duplicated it around a central point. However, I have chosen to make the central point quite close to the point in which the duplicating is originating from. Therefore it has created this model without a hole in the middle.

As a visual association, it reminds me of the blade inside my electric razor.

Left hand-side view of this model. With the shadows applied, it really creates a sense of depth in the model. To expand on this, depending on the viewer it can be seen as the middle point coming out of the screen or going into the model further. 

Right hand-side view, due to the way that I have made the shadow style in this model, you can see all of the detail of the overlapping models as they are rotated around the central pivot point.

Just a perspective view showing the different layers which help to evoke depth in the model 

This was another development, well actually more of an experiment / trial. I have used the same concept as the model above except moved the central pivot point further away from the original model before duplicating. This changes the whole shape of the resulting model. I then duplicated it and rotated so it was perpendicular (but still on an angle) to its partner and made the two pass through one another. 

Top View of the model. 

Back View of the model. It is clearer in this screenshot how the two models intersect one another and the angle that the duplicated model is on to create the overall model. I felt that if I made the second model exactly perpendicular to the first, it would have not had as much quirkiness as it does when it is on an angle.

Perspective View

Another perspective view

I feel that this will be my overall final 3D model for the design principle of symmetry. I really like this model and how it came out. I have used the same method as the two previous models, (all using the first model above as the basis) except I did not duplicate around the central pivot as many times as I had in the two previous developments. I also had a greater distance to pivot around. These are how the gaps in the model were formed.

Front View of the model. These are the gaps I was referring to in the previous description. Having the gaps will allow me to pass light or background - whatever that may be, through to make it more realistic and believable that my model could be wherever the situation I decide to contextualise it in. Again like the model earlier in this post, the shadows in this model help to evoke the sense of depth which will also help it be more believable when applied in a context.

Finally, a perspective view of the model showing the depth:
