This song is actually pretty straightforward. There’s no particular section that’s really tricky.
Use the sustain pedal throughout the song, especially for that octave bass line riff that comes right at the beginning and repeats throughout the song. For measures 25-40, you should reset the sustain pedal every measure.
Again, since this song is pretty simple, see if you can use things like dynamics and tempo to make it more interesting. You can make sections louder or softer, slower or faster. Try it a few different ways and see what you like.
