The patch file you submitted was corrupt, the ROM that I patched became 991 KB large, which is probably not a good sign. The title screen was glitched, Mario immediately died after the game started.
Please test your patched before uploading.

Also, two other things:
- please give a hack length next time, it's definitely useful.
- the screenshots you uploaded weren't proper, read this to learn how to make good screenshots (just like I said in your other hack's removal log)

This hack still needs a lot of improvement. Let's see the main problems.

First off, the screenshots you uploaded weren't proper. Read this to learn how to make proper screenshots.

Cutoff/graphical errors



Water + "?" blocks = cutoff.



A random missing tile? O_o



Ground + pipes = cutoff.



Note blocks get glitchy when Mario hits them, because you're using the castle sprite set (note block isn't compatible with that).



For some reason, the springboard looks like a glitched Goomba in the item box.

Palette problems



The OW border could use a lot of better colors. Mario's sprite is cutoff, and the life number looks weird.



Same goes to the save prompt.



These yellow flashing bricks look rather odd. Why don't you use a custom palette?

Other





Bad entrance FG/BG positions. This picture might help when fixing these.



Don't put Yoshi Coins on on Sub-screen Boundaries!



Floating Munchers = big no.



This level really reminds me on Donut Plains 1...



Due the bad sprite memory (Lakitu head in LM), Mario and the Piranha Plant disappear here for a while.



Using invisible coin blocks in Switch Palaces is not a very good idea.



Seriously? If I don't move, I instantly die here? That's not really nice.

And this goes on.
