You have a bad FG and a bad Sprite palette. Go on the rainbow star in LM, change "FG Palette" until you have the Ghost House one and change Sprite Palette until the Boo Buddies look like the other boos.
While we are at it, make something so that you can see if a boo is a NPC or an enemy.
Also, I think the trees in the BG aren't fitting - trees in a Ghost House
You come out of the pipe 2 tiles too high. If you have a vertical pipe exiit setting, place Mario so that he is IN the pipe and his head/feet is/are just touching the pipe end. Look:
QuoteUnexpected end tag (</pre>) at 737, expected </div>Tag (div) was not closed.
O = Pipe with exit on top - Place Mario at I

Bad FG/BG Starting Position. Go on the panel where you adjust where Mario starts, and change FG and BG to C0.
