Pretty airtight all around. Only things I would suggest would be to wavedash less and moonwalk more in its place. Link's wavedash length is okay for doing some good spacing, but it's really sluggish, and moonwalking has more transitions out of it during any point of performing the technique.
I would also bomb punt a little less. It's a neat trick, and has some unique applications (lay bomb, throw out zAir within striking distance of opponent, laugh at pressure from bomb and zAir hitting them all at once), but it too is a technique that requires a large amount of time to set up. Not only that, but the positioning you have to be in to perform the short-hop-bomb-punt is very specific, and limits your own movement. Just opt instead for AGT bombs. A slow Link is a dead one.
Another thing I would consider is standing still as you throw the boomerang more often. I know that my whole post has been about removing the slower options, but if you're not immediately going into a combo with 'rang, and just trying to gain stage control, throwing it while standing still can be more effective. It does not commit you to a jump arc, meaning that you force a reaction out of your opponent without giving up your own position.
And, lastly, you had some good use of your bombs. I'm a bomb freak, myself, so much so that my go-to pattern is to lay two out, and throw one straight up in the air and hide out under it until it comes down. It gives you a sort of protective wall. An opponent who can't move is one that you've got good control over, and the constant threat of bombs everywhere is one way Link can put that kind of pressure on that people don't always realize is available to him. He can AGT them off of platforms, instant toss them off of the ground, or just leave them there, all at any time he wants. And just having a bomb in the air with the threat of coming down is enough to make most opponents very cautious of jumping in on you, giving you a form of air control.
