Wow! This is really cool! Happy to hear I helped. I like all the work you did on the rest of the game world. I also think the SMB3 sprite is a solid choice.
I'm planning to update the game with more of Bobbom Battlefield in the next week or so, so if you need anything else, feel free to take it (I'm curious what you'll think of my recreation of SM64 trees).
What engine or tools are you using? I was just using vanilla GB Studio.
