With fixing the lay-out I mean the (visual) lay-out of the score. In the PDF you attached to your post the lay-out could (or sometimes must) be improved at some places.
These are all places where you should change the score to ordered sheet music that is easy to read:
Mm. 1 - 4: This passage in the piano must be laid-out again, because the notes, articulation and dynamic markings and rest are overlapping each other, which makes it very hard to read (while playing).
Mm. 19 - 20. Piano. Crescendo. This crescendo that touches the notes is not very disturbing, but if you can easily change it, change it.
Mm. 53 - 54. Piano. Legato bow. Not very disturbing, but if you can easily change it, change it.
There are some more details, but I don't want to be that person that runs down on the details.
I hope this helps!
