3D checker pattern has a modern take on a traditional pattern - resembles blocks or units symbolic of properties. The one highlighted blue gives the design a focal point.
Not a big fan of the checker pattern. Reminds me of a lot of tech companies I've seen. I'm looking for something more earthy and grounded. I like the thought of the X and the symbols in #25 and #26 but maybe make them a little weathered and detailed. Think ancient artifact maybe.
#87 Using the "O" with a flag to reinforce the "Tradition and honour" aspect. The O reinforces your name and the icon works on its own if that need should arise - as a watermark background for example.
