You could take a look at how this one was done and see if you can improve on it, or take some ideas and try remaking a different level from the same game.

Some more really good course from one of the SMM players I’m following.
Mt. Yoshimanjaro

Slip-Slide Spires

This level is one I made.

i am so tempted to get a wii u for this game
So I’ve got the game but I’m still waiting on my Wii U to be delivered. 
I’ve been playing waaay too much Mario Maker lately.
Here’s a stage I just finished.
Dippy Mole Mania -** 6DDF-0000-006B-EE87**
I tried to design it with experienced and inexperienced players in mind. I also have been playing around with rewarding exploration without punishing a player who would rather barrel through the stage. Don’t think I entirely succeeded but it was fun to make.
(Good. Now just stare at the disc intently like that girl from Audition until your Wii U arrives.)
Updated the first post again with the three stages that ReggieHadoken posted, though both my curiosity and OCD want to know the name of the person whom he’s following that the two stages he just posted belong to so I can put said name down in the front post as well.
30 minutes plus to set up a Wii U?! But it has arrived. And I shall begin my quest. 
Huh. You were right about nostalgia, @Zebster. My NSMB 1-1 level has 3 stars already.
It’s not much but it’s more than I’ve gotten on my other levels in the same span of time.
Fire Temple, Hyrule 3, and the updated Forest Temple all have 0 clears though at the moment…interesting.
Pauloot is the name.
This game is THE BOMB. Already I’m having a world of fun creating my OWN Mario levels.
(See? I told you Audition levels of staring would work.)
Thanks, LordWilliam1234. I’ve added that name to the front page within the relevant sentence.
I’ve also added Dungeonman to the front page between Davidstar and Femto since I didn’t see his post when I updated about half an hour ago due to him posting only a minute before I posted.
I’m still working on Forest Temple. I found the star through the pipe and got past the big boo circles, only to find myself stranded up on top of a pipe in the air with no idea where the hell to go to next. I took a leap of faith and fell into the abyss. FML.
Silly question, but how do we unlock the alternate styles of Mario and things in general? I’ve played it for well over an hour now, yet I have not unlocked anything.
In level editor, just drag a ton of stuff across the map. Do that with all the tools you’ve got and it will speed up the process of unlocking.
Thanks for posting the name to those levels I was putting up, LordWilliam. I was considering doing that, but I wasn’t sure if anyone was interested in knowing. I’ll add names to anyone else’s stages I come across from here on out.
I gone done another one.
The wroÔng PïPéÉ - E7CE-0000-0082-56A0
The path ahead seems blocked. Wonder if going down the pipe does anything to the level…
Piiiicture:
Spoiler
I thought I heard somewhere that Nintendo released a patch to make all Mario Maker stage dev content available. Is this true?
You can unlock everything in under a half hour, but you need to make use of all the tools while building stages.
ALL of them.
Not true here in Europe at least. I’ve started playing the game about 40 minutes ago but I still had to unlock everything manually.
Did another recreation:
Ninja Gaiden 1-1 (NES)
EDC0-0000-0086-03EF
(It’s not like it’s unusual for Europe to be put last when it comes to video games though, as unfortunate that is for most gamers there.)
To “answer” your question, @Hotobu, I had heard the same thing and I thought it was confirmed to be part of the first or second update that Nintendo put out. Given I have no way of playing the game myself currently, however, I cannot actually confirm this definitively at present.
As I have nothing much else to say right now, I’ll just leave another “Top 5” here for now, this time from Polygon. It would seem that the “Winners don’t do shrooms” stage made both of the ones I’ve watched so far:
Okay. Added to the front page.
4 days later and Fire Temple, Hyrule 3, and the re-uploaded Forest Temple still have 0 clears.
Here I thought I was making the levels too easy. Even my NSMB 1-1 level has only a 76% clear rate.
Like, seriously, this is where people are dying on it:

Three of those are death by Goomba, two are falling into a pit that’s only 2 blocks wide. :bluu:
