Decent job, but there's quite a few things which need fixing.
Okay, here goes nothing. Glad I had coffee earlier.. (hehe I'm not sleeping)
Quite a few of these remarks are going to be personal preference for various reasons. Things you must/really should do will be bolded, and things you may want to consider will be italicized.
Formatting:
- Lower the first system, raise the musical direction marking (good on you for having one, by the way!).
- The interpretation note at the bottom of page 1 is redundant; most skilled pianists (which you would have to be to play this sheet in any case) would know to emphasize a melody line over octave tremolos. If you must make sure it is quieter, use a different dynamic in each staff, placing them above the top staff and below the bottom staff.
- Standardize your systems; you've got 6 measures in the second system and 3 in the fifth.
Arranging:
- First measure: Lower the accompaniment Cs to below their respective dyads. This gives a "fuller" texture otherwise not capable from one instrument, and also solves part of your clashing problem. In addition, let the bottom voices hold out with the use of a second layer.
- Measures 1-4: Replace the hairpin with a cresc. marking (for aesthetic reasons)
- Measure 4 (a): Replace the f p with a Fp (forte-piano). This makes it much clearer what you want. Better yet, since you have a crescendo before hand, you could do a sfp (sforzando-piano).
- Measure 4 (b): Get rid of the top c on the octave on beat 1.5. This allows for a cleaner texture in that little "passing" moment; the bit where the dominant note is repeated in different octaves. To allow this to be clearer to the performer, along with the fp/sfp (depending on what you pick or if a Mod deems it unnecessary), I would eliminate the octave; if anything, I would put it on the downbeat to give contrast.
- Measure 8, beat 2: make the C-Db tremolo a trill.
- Measure 9: Bring your LH down an octave to give both a better texture and a playable sheet
- Measure 12: The 3 note sequence leading into measure 13 is a 16th triplet.
- Measures 13 through 15: Like with the introduction, let the bottom voices hold out by use of layering. This is reflected in the original, as well.
- Measure 20: Make the last note of your RH match the value of the last note of your LH, since they're ending in sync and there isn't an obvious lingering of one voice while another drops out.
- Measures 21 through 23: This is where your sheet suffers most from cluttering. Drop it down an octave to not only detangle your hands, but also give a different timbre to the melody while you have the octave accompaniment.
Also, I know I said it already, but delete the performance mark (and replace it with two dynamic markings if you're so inclined).
- Measure 24: Drop the chromatic line down an octave for the same reason as above.
- Measure 28: Rewrite the RH part an octave down with an 8va sign, and hide the whole rest from the other treble staff for a cleaner transition. Also, increase the spacing a little on this system, as measures 29 through 31 are cramped. You have the same problem in the following system, albeit not as cramped.
- Measure 32: Ditto to the above.
That's about all I can think of right now. Hopefully this can help speed things up.
Btw, sorry if I come off as pissed; you did a good job! There's just some stuff that needs reworking.
