Looking at the second half of the 4th beat, I'm curious how someone might recommend fingering the right hand of this particular phrase. The written fingerings are my best guesses. The positions feel comfortable and seem like they would work at a higher speed (the piece calls for q = 80). The (1 4)-5-(1 4)-2-3 fingering seems more natural, but (1 3)-4-(1 3)-2-3 variation takes advantage of the strength of the 3rd finger.
I understand that fingering is subjective to personal preference, hand size, etc., but there are also well-established patterns for certain phrases that tend to work better. Is there any sort of precedence in the piano literature with a similar sort of phrase or fingering that I could reference? This piece itself is not part of the standard repertoire, so there aren't really other sources to consult.
