If you're under this impression you should look into what's wrong with the level and try to improve it, rather than posting it in its flawed state, knowing you could've made it better.
After playing through this, I have to agree that this is far from an interesting level. It's not the worst I've seen, but it's just overall pretty bland and boring.
The first half heavily reminds me of overworld segments in Super Mario Bros 1 and World. The only thing which gives me the illusion of this taking place in a cave is the lava which you introduce in the second half of the first section. In fact I think the Mario World Grass tileset suits this level better:
(I have removed the lava because it's essentially a pit)
Aside from that, I found that one of your stalagmites replaces the SMB3 bush bgo. While playing, it gets cut-off, looking like a small rock floating in midair. It's not possible to resize background objects and I recommend replacing background-10.gif instead.
The 2nd half shakes the level up completely, however it lacks any substance. Fish and coins seem to be placed randomly, creating little to no challenge. Seeing as this section tries to resemble underwater segments from Mario World, I recommend checking out how water segments in that game played and thinking about how to translate them into SMBX.
Lastly, I wish the fetch quest for the key didn't exist. It's completely pointless and does nothing but drag the level on without adding anything. You give the player a flower at the start of the section, so you could assume they took out all the fish in their way. I think a standard goal tape instead of the key would've been much better.
Moved to trash can.
