For me, giving verdicts is cumbersome, because it gives me the feeling of being judging, something that I don't consider fair. But taking into account your tastes and decisions.

It seems to me that if the letters are improved so as not to have to guess what it says and if you intend to charge in Bitcoin, then add something that identifies it, although there are already stickers with "BITCOIN ACCEPTED HERE"

IT SEEMS VERY GOOD TO ME.

If you make modifications later, I would like to see how it ended up.
