I'll be charitable, since this was your first mod and you didn't exactly give yourself much time. Still, this one isn't great.
The core idea as you originally intended it sounds cool, but that's not really what this ended up being. It's really just the Chapter 4 cooking intermission followed by a Bowser fight. However, the mod still demonstrates a light amount of script editing to make the cooking part work on its own, and some asm patches being used to give Mario the partners and badges.
The one modding discipline you've clearly mastered is string editing, but even that doesn't show very well. Once the cooking part is over and the Bowser sequence begins, there's like three edited lines and the rest are all vanilla. Basically nothing in the epilogue is edited.
Overall I'm not a fan, but I hope that now that you don't have to worry about meeting a deadline anymore, you'll take the time to flesh out your original concept and make something awesome!
