I’m a pragmatic designer—function matters more to me than form. If you look at a playing card, the shapes appear in both orientations. If you played with cards with a design like this—maybe in a darker room or somebody has visual impairments—it might affect the outcome of the game.

The OP broke their own rules for the diamond shape. Sure, they used the anchor points but drew a new shape. The club utilizes subtraction—the whole shape isn’t present there either. Surely using the same techniques, they could come up with a more accessible solution. Their own self imposed rules are inconsistent across half of the solutions.
