Solid.
I didn't really see many bad habits. Try to mix up your recovery options from the ledge, you seemed to almost always fair from it. It's nice if you hit with it, as it can lead to a grab, dsmash, or usmash, but it has mediocre priority is easily shieldgrabable or spaceable by the opponent. Also, don't rely on his shield quite as much, it's not especially good. Pika has a good dash, so a few of the times that you shielded something you could have easily dashdanced away and then back for a jc grab/usmash before they recovered from the lag of their attack.
Against links, you can also often mess up their hookshot recovery with jolts. You can snipe them with it right when they hookshot, or on stages with flat sides you can let the jolt follow the stage and hit them while they're hanging from the side. Then, edgehog, space an fsmash right at the edge, or chase him out with a nair/dair.
