Random advice:
Make sure your map is timed properly, else as a new mapper you're just wasting your time IMO. Watch a pishifat video or something on how to time the map correctly, or you could download a song from the
Featured artist page that you like, as they're already timed for you.
If you really want to become good at mapping, map lots of different songs, dont get too caught up with one map cause in the end IMO it wont help you that much until you're better at mapping.
Map moreMusic representation is everything, so make sure you're at least placing notes where there are notes in the song !
Idk just watch pishifat videos
