How about instead of having the black background for the hand icons, we just completely remove them and have just the hand icon with no black square?
I don't know about others but in my opinion, it would look a hell lot better. Also I tried once removing the black square and instead just having the hand icon but for some reason it doens't overwrite inside the game.
Would be cool to have this as an official thing though, What do you guys think?

I think it's a great idea. But why not add both and choose you're custom hand in options
