Tip: Layer 3 backgrounds and tides disappear when you hit a message box, so plan your level around that. For example, you can add a sublevel without layer 3 at the start/midpoint, and include your message there.
Here's a level called "A Vanilla Night." It's nothing too fancy - just a SMW-themed level for the most part. I had a few people test it on the IRC channel about a week ago, and I've also submitted it to Quality Control. I would appreciate any additional feedback.
This level feels very unbalanced, mainly because the level doesn't seem to know if it wants to be an easy beginner's level or a moderately difficult level. Most yoshi coins are easy to find, but one of the first ones is found by a hidden vine block with no indication other than the fact it's on terrain a bit higher than the ground. There's a lot of basic enemies but there's also points where there's a lot of unkillable enemies unless you have the fire flower. The level itself is fairly short but most of the level is a line-guided platform with Mario dealing with three homing paratroopas (those exist in smbx apparently >_>). Not to mention at the end there's a suprise Banzai Bill with no cannon. That wasn't cool. The concept of an SMW level is nice and would definitely help tie in this project to smwc, but the level needs a lot of redesigning to get a solid idea of what it wants to be.
As for the visuals and music, they're pretty standard for an smbx level. I don't really mind them, though some people might be turned off by the...mario-ness I guess since a lot of people like lots of custom things. It's not a problem for me though so keep it as is if you like it.
It's great that you were enthusiastic, but I have to agree with DB. The level doesn't have much going for it and based on what I've seen in your other thread, you're capable of making much better/more exciting levels than this.
To be honest, I'd leave this one out and focus on your other one (and any future ones you decide to make).
While this level could be accepted and would fit nicely on World 3, i have to agree with what was posted previously: It feels too bland. It definitely could have some more thought put on its design, as it feels a bit rushed right now.
I'm not sure if m4sterbr0s is still interested in fixing this, but it's not really acceptable as it is now.
