Hi Cetlan, and welcome to TASVideos! I'll be reviewing your work today.
For starters, I want to point out that while the goal of minimum banana collection is perfectly acceptable for Alternative, there are some complications with how the movie is defined, specifically when it comes to "Glitchless". Unlike DKC1, DKC2 doesn't have a definition for glitchless, since all major glitches can be plainly avoided by aiming for the warpless category, but your specific goal would benefit from warps and your movie actually uses them. Neither you nor the video you link (which is not linked properly on the embed) provide an adequate definition for glitchless for this category. We can easily rule out things like wrong warps, but stuff like Team Throw Super Jumps, which would be benefitial for this category in several levels, is arguable either way and in my opinion would contribute to the stated goal. The submission text lacks any info on this, and as the author we expect you to be as informative as possible, especially when making decisions not seen in prior work.
More worringly however, this movie has serious optimization issues. One is immediately apparent in Pirate Panic: you don't have to grab all crates and barrels while rolling. They can be bypassed by releasing the Y button for a couple frames. This is a very well known technique, used in TAS and RTA runs alike.
You're also forced to grab a barrel anyway, and you do to obtain Dixie, but you throw away the barrel in a slow manner. It's possible to throw the barrel offscreen in a way that removes the slow animation of the other Kong jumping towards you.
In Mainbrace Mayhem, you miss many optimizations. For one, you only need to crouch for a total of two frames to avoid the first banana, as Diddy still has its lower hitbox until he fully finishes uncrouching. Two, you can cancel your roll into a team up, which greatly diminishes momentum and would eliminate the need to walk back to get to position for the first team throw. Third, you can actually use a strategy similar to the one seen in the 102% published movie and do your second Team Throw close to the letter K. With proper positioning, Dixie will land near the banana coin and then you can jump over the six bananas nearby without collecting any.
(I tested all of this myself on a simple improvement movie, but due to unforseeable issues it was corrupted and I cannot recover it)
There's a general lack of care in several parts, such as bonking into corners during Lockjaw's Locker, not jumping out of ropes which is much faster than climbing them, or even just not switching from Dixie to Diddy when applicable. I'm not sure how much research you did before committing to a submission, but i assure you, there's plenty more to do and learn for this. Under those conditions, I cannot recommend for a judge to accept this movie.
I can see you put a decent amount of effort on the movie itself (judging by the amount of rerecords), so I believe this to be a lack of research. Don't be afraid to step in the shoulders of those before you! DKC2 has a large speedrunning community and several beautiful movies published on this site, which are under Creative Commons and you can download and use (with proper credit). Use them! Research your game as far as you can go, join communities that you think can help you, be curious and try things. You can do a lot better than this, and I'm looking forward to you doing so.
