Bigger is better

So, this is where we left off:

Seven cans high and seven cans wide. Hmm, I think I can do better than that. And so I started to think on how I could add more layers to the tree. This was one of the first ideas that came to me:

I started building the lower 'ring'.

Two can wide.
And this is how it should look when it will be finished.

The lower 2 layers that will be added.

There we go! It looks a lot better than it did before.
