Really like the theme and execution especially with the life ring, prop (brilliant) and navigation lights. Been thinking hard to see if I can offer any advice.
Design tweaks:
Make the inner ring thicker so the color is more defined.
Put the number in the outer ring so it’s another place to read. So two numbers and two table identifiers.
I have always thought about doing a Jack, King, Queen, Joker set. But that’s because I have the suit ones already. Not exactly sure why I need an eight table set but think that would be a complete set for me.
