Personally, I think that transition in the first replay is amazing, you just need to get the axis of that cork right and you're gonna probably even be able to double. A good way to get the axis right is to make sure that your ankle is pushing in the right direction to send you into the flip, and just really concentrate on what each part of your body is doing to send you into the cork motion.
In the second replay, I think that would be a gumbi into a cork, and that cork definitely looks like an improvement to the one in your last replay
