This time, the second part of this Prelude... my brain just isn't having it :/ I think it might be the bizare "1.5" Notes that are connected to the... Semi-Quaver? I think this combined with the chord jump just isn't working for me... is this just down to practise, or is there any particular trick to it?
And another question about it while I'm at it, there are 3 sets of quavers joined up, that twice are "selected" and have a small "3" above them. From what I can tell, you jam these 3 effectively into 2 quaver beats (or a single regular beat I guess)? But I gotta say, that If I'm right, the second set, where it's: E, down to E, and up to A... sounds wrong :/
OK, there are actually quite a few "tricky" spots in this piece if you haven't had any prior experience with these things and no teacher to ask. I'll start with a few that come to mind right away. You can tell me what else there is, but please use measure numbers and note names. I have a hard time figuring out what exactly you are referring to.
1. As trivial as it sounds, the first three notes are quite difficult to play rhythmically correctly. Make sure you are counting a full measure in your head before you start, just to get the feel for the tempo.
2. Since you don't have a pedal, I won't say anything else about it than I have already said.
3. Measure 11: play the grace note on the beat, and the A in between the two chords in the left hand
4. Measure 12 (and also meeasure 18): the three notes that have a bracket with the number "3" in the middle form a so-called "triplet". These three notes take up the space of one beat, i.e. they must be played within one beat. Generally, one can have any kind of "tuplet", 5, 7, ..., 19...
5. Have you figured out the turn in measure 16? It's quite tricky to play this section rhythmically correctly. This section all the way to the end of measure 18 is supposed to be played "stretto". Start your Google engine

6. the "bizare "1.5" Notes that are connected to the... Semi-Quaver?" (e.g. measure 16) are dotted eigth notes. The sixteenth note (semi-quaver) is to be played in between the second and the third chord in that measure.
7. Measure 18 is the trickiest in terms of rhythm. First, figure out exactly what the rhythm is (3 against 2), then practice it slowly away from the piano (e.g. by clapping) to get the hang of it, then play it.
8. Measure 21 to the end is supposed to be played smorzando (Google)
9. Measure 23: Make sure your audience doesn't think the piece is over when you "play" the rest with the fermata.
10. If the chords in the last two measures are too big, you can drop the bottom notes. It won't be terrible, and you won't ruin your hands. But if you can play them, great!
Let me know if that helps at all.
