So, I played your level, and this is my review for it. Enjoy.
Review - "Super Mario Land 2: Birabuto Kingdoom: 1 world 1 level (btw, it's kingdom and not kingdoom.

)
Level Design and NPC placement (12/15)
So, when I played your level, one thing that was really driving me crazy was this:
Look at the SMB3 desert stone thing block down there. You just made it go under that sand dune and cut off. Then there is a castle tile (?) and the sandstone goes under the sand (?!).
But the rest of the level was pretty well designed and fun to play. Although you should probably get rid of all those multi-coin question blocks, as it is really annoying to jump ten times against the same block many times in the same level.
You should probably have placed more enemies in more difficult places, as right now the landscape seems pretty bland in NPC placement terms.
Atmosphere, music choice and graphics (7/10)
The few custom graphics that were actually used blended very good with the atmosphere and these bomb koopas are really clever.

The desert atmosphere was average, as there were no special BGOs to underline the desert itself, but the BGOs that were used in this level are placed well and fitting. Good work there.
The music though, it was just not fitting. I don't care whether this is the original track or not, but orchestral, fast music fits more into a sky level than in a desert.
All in all (19/25)
This level was an average level for a remake, but it lacked in something that made the level special or outstanding. A gimmick or something to distinguish it from all the other remixes of original levels. Good job nonetheless.
(7,6/10)
