Here's a custom level I made!
You're cutting off the start of the level by having it that close to the zone border.
The bottom of the level is also cut off some, you need at least 3 blocks of space there for it to not look like crap in game, and the edges need extended several blocks below the line so that people don't slip off the level when walljumping in the pit.
Your terrain isn't drawn correctly. the underhang pieces are incorrect. Look at my New Classic 1-3.
Delete the super guide block. It's not needed, because the replays won't work. Pipe entrances go on the top left corner of the pipe's edge, not in the middle.
I can't tell what Location 1 is supposed to do (maybe it has something to do with the 38 a little further down).
The pink block isn't what you want to have there, that's line controlled. Look at retail 1-5 to see how to make spinning blocks like what you want.
Plus, it looks like you left the cloud areas that are part of 1-1, including the sprites.
Come on folks, play your levels at least once. Strive to make them as good as Nintendo's both visually and functionally.
