Measure 27-34 is the most difficult section. The right hand is the same as the beginning, but the left hand is more complicated. Practice the left hand by itself for awhile until you can play it without mistakes.
In general, you should reset the sustain pedal every measure. Do not use the sustain pedal during measures 18-25 and measures 35-42.
When you get to the section starting at measure 18, make sure you leave space between the notes in the left hand. The quarter notes have rests in between them in measure 18, and then the first two notes of measure 19 have staccato dots which tell you to play them short. Listen to the video to hear how it’s supposed to sound.
