Yeah I really need help with playing as this character >_<. I only played him G1, but I'm sure there are a lot of things I was doing wrong in that game. Tips would be LOVELY!!
The main thing I'd say is that if you see someone airdodge into you, it would probably be better to use dtilt or grab instead of fsmash, because the start up on fsmash is longer and they can still be knocked out of the fsmash before the final hit. Everything else showed that your DHD is pretty sweet! :D
Edit: Actually, I'm watching the last game now, and I noticed that this game specifically you're relying a lot on your projectiles (it seems like more than you were last game), and the Captain Falcon started adapting to them. There were a few times where you would clay pidgeon when Captain Falcon was right above you, or Can when he's right next to you, and Falcon would just grab you for it consistently. It may be better to either run away and re-set up your positioning or to grab/jab him as he falls into the ground. I could be wrong though.
You also weren't using your aerial game nearly as much last game as you were the second game, and that was part of what put you ahead of the Falcon imo.
