This level was actually rather pleasant!
Design- The design of the level was nice. It wasn't too confusing, but not exactly TOO linear, so it wasn't boring. If there was one thing I liked about the level, it was that even though you had to follow a path, you seemed to have a variety of going up or down some to get extra coins and some Yoshi coins! The level was also long too. It wasn't too long to the point where I was wondering when it was going to end. Levels that are too long become more of a hassle than an enjoyable experience. Your level was a pretty perfect length! If there was one thing I really do kind of want to complain about, it's the clash of the SMB2 enemies. They seemed a bit out of place. I typically don't see clash as an issue unless it's too obnoxious, but I didn't like how there were NO SMB2 enemies (Other than the hedgehogs) until the last section, which was randomly abrupt. The only fitting SMB2 enemies you had in there were the hedgehogs.
Scenery- The scenery was absolutely beautiful. All of the custom graphics were really awesome and well put in place. If there was one thing that slightly disappointed me, was that I saw how all out this level went with the custom graphics, yet some of the background object were still the same old graphics. Not too bad though, it was just more of a disappointment.
Replay Value- I could totally see myself playing this level again. I like to play user-made levels to help inspire me to make my own, and I would probably play this level again sometime if I need help with a creative idea! Would recommend playing.
Misc- As I said, the custom graphics were really nice, but I wish there was more to replace the graphics you didn't replace i.e. the SMB3 sizables, SMB3 mini bushes, but whatever, no biggie. The music fit the level really well. It gave the level more of a majestic feel, and I was hoping it would! Nice one with the song choice. It sounded so familiar too, but I couldn't figure it out . . .
PROS:
- Nice music
- Nice length of level
- Nice custom graphics
- Yoshi coins!
- The screenshot below shows an obstacle I really enjoyed!

I really liked the idea of some of the upside down water you had in the level, because it gave the level more of a magical feel to it, like the forest is majestic, which also accented the song
CONS:
- Little amount of power-ups
- Clashing enemies
- The fact that if you fall off the mushrooms that jolt you up, you can't pass the part of the level or finish the level.
- Below are some screenshots with complains

It pissed me of when I got stuck here . . . It was the first real error I encountered in your level. I ended up having to erase the blocks to get out =/

This part seemed like a bit too much all in one small area. An unnecessary amount of note blocks and breakable SMB3 blocks . . .

This looked kind of awkward. I suggest not using as many color blocks. You don't need to have a complete path up to the pipe, and furthermore the pipe didn't need to be blocked considering you can't get up there anyways. I suggest making it like this:

OVERALL.
7.5/10
Moved to Pretty good levels!
