Looks good! I have a few notation things.
- You are hiding beat 3 in a couple measures such as measure 4 and 11. You should have the quarter note as tied eighth notes.
- I don't think the 8vb's are necessary. F is not hard to read with ledger lines. You have other F's throughout the piece with ledger lines.
- Is there a reason you have the key change in the second measure? I think it would look cleaner to start out in the key and have accidentals in the first measure.
