Thank you. I'm glad you liked the story.
About the drawings... I might change some things, but not everything.

Thanks! Yeah, the transitions are a little abrupt but it was written to time directly to action on screen and there was very little wiggle room. With this tempo I ended up having to lop a few beats off of one phrase and then I had like 3 and a half bars to fit a B section before the recapitulation. I tried to obscure the timing by shifting into a hemiola pattern which blurred the downbeat so it eventually felt like it was in 3 so when I went back into 4/4 it wasn't as obvious that I had dropped a few beats. Meanwhile I was jockeying the tempo the entire time to get everything to match the onscreen cuts.

Do you have any specific suggestions of how I could go about making the transitions more seamless without changing the tempo map?

Thanks, I have edited it

Thanks, I see that but I will not edit that because it was my first Mario I has painted on a computer
