Hi Raiden, sick blue bowser skin! Here are just a couple of my thoughts on the game you posted. I am by no means an expert player, but maybe you'll find them useful.
Crouch canceling: You use this to great effect to move through razor leaf and stuff his approaches. I would be careful about relying on it too much as your opponent may adapt and start grabbing more or baiting out the d-tilt and punishing. But in this match it worked very well!
Edge guarding: Don't F-smash at the edge, especially vs tether characters but also just in general. It's almost never a good edge guarding option unless you have the hard read and are looking for a quick kill or some disrespect. One time you had a cool reverse kk ledge grab but you got up too early. Just hold on until the tether character is forced to recover and punish accordingly (like ledge hop waveland d-smash).
Rolling: It's not as scrubby as everyone makes it seem, sometimes it's a good option. That being said, when getting pressured, up-b OoS is often a better option, especially with a ledge in reach. It also seems like you're using it not just to avoid pressure but also as a safe way to traverse the stage. The problem is that, while rolling away may be safe, it doesn't leave you with any options to punish; it's like you're constantly resetting to neutral (obviously not one of bowser's strengths). Try mixing in more wavedashes and wavelands to have movement that is safe, precise,
and can be quickly acted out of to punish your opponent when they misstep. For instance, on PS2 I like wavelanding off the platforms and mixing up fair and fire to catch my opponent off guard. (Chaos_Blasta has some sick Bowser movement if you scroll up a couple posts to his Paragon vids).
Jab and D-tilt 2: Remember that you don't always have to input the second jab or d-tilt. If the first one doesn't connect, it's unlikely the second one will unless they run into it. And even if the first one does hit, sometimes there are better follow up options. For instance, after hitting jab 1 you can follow up with cc jab 1, d-tilt, or grab (depending on percent, weight, DI, etc.). Just something to keep in mind.
Aerials: You play a surprisingly grounded bowser. Honestly I can't think of a single use of fair, or nair for that matter, or bair...or dair...dang. Okay, I just skimmed through the match again and still didn't see a single aerial except for two or three up-airs. I don't think this is a bad thing necessarily; it's just an observation. It worked pretty well for you this game by making you much less susceptible to razor leaf which he relies on a lot. Yeah, I don't know, just something to think about I guess. I definitely respect your commitment to your strategy.
Thanks for posting! Hopefully that was helpful.
PS: If you get a chance, get some games in with Big E (an Ike player and friend of mine who also just transferred to UCSD). He's played my bowser a lot and will teach you a thing or two about the matchup (and then switch to sheik or metaknight if you start having too much fun, haha).
