Super Mario Maker level question

[LarBob]

I'm putting this here because I don't want it to be seen as advertising my course or anything. I made a course called doku (I was reminiscing on MKDS...) and I noticed it has 0/62 clears. It took me a while to beat it to upload it. I was wondering if you guys think it is too hard, too easy, etc. and what I could do to improve my level design as I've only really been messing with this for a few days. I'd really love suggestions.

Thank you.

I just finished beating it and it was hard, it was easy to slip up or miss the bullet bills and fall off, the main reason I believe no one else has beaten it is because of the note block under the door, you had to time it right and it is difficult if you didn't take a bullet bill and not to mention the bounce of the note block doesn't let you open the door. it is hard but it was also challenging for me since I did not give up.
