I see the issue. I would play the first three notes of each group of four in the left hand, as the fourth note is a repetition. Another way would be to play it an octave higher so it is clearer, anything below 5th octave C. It is too muddy as written, but it depends on the score, which you can download. Or you could double the right hand in the bass, as long as it is the same chord-tones. Or, play chords on the beat in the area written.
