This was my first attempt which I don't think sat right at all. I undid the bottom row of it and put in an extra vertical, so there was 5 instead of 4 and tried it again.
This was the attempt with the five verticals, I still don't think that it looks amazing but it works much better than the previous one. I think I will carry on with it and put some more tiers one it to see how it turns out.
