First of all, it looks great, good job there.
It works as far as I can tell but there was one minor bug. An odd thing happened on one of my hands. Having discarded to the crib and before we start playing cards to the table, I found that I only have three cards in my hand. Where the leftmost card was, I now have a blank space and can only see the table. When I played a 6 to the table, the missing card (a 7) suddenly became visible in the correct place in my hand (far right).
A minor grammar Nazi quibble is that when the instruction tell me to discard two cards to "Your crib", the Y ought to be lower case.
When the hands and cribs are being evaluated, the cards flash by too quickly for me to try to work out why my hand is worth 10 points, it would be nice if this were slower or I, at least, had an option to slow this down. I was trying to teach a family member how to play but it's tricky when the cards are only visible for a short time. It would also help someone learning the game to have a text description of why points are being awarded even if it's only in the game log.
