Hello.
I left very quietly in the early early morning, waving to the fisherman…
Do you mean to have only one "early" and "fishermen"?
We don’t cry for the sea”
Missing a period.
dad told me so in a letter
What does this mean? Also, since you're talking about "dad" as a proper noun, you should probably capitalize it.
Tonight I had another dream
Sounds like a new diary entry, and thus a new heading.
I’m still alive, there’s someone in here, I thought to say. But the door must have already been painted shut. The smell of it is getting worse.
What do you mean to say here…? I am assuming you are trying to foreshadow the ending, but the way this is worded is confusing.
Mothers is polished oak with red lining
Missing an apostrophe
The morning my mother found a new shell the woman took me to the beach.
Add a comma after "shell".
Dear Rosie, our love, / do not cry for the sea.
Put this in a quote block to separate it from the main text.
That is the majority of the language errors. Reread to be safe.
JUDGEMENT
The story concept is strong, but like I've said before, you're lacking good story flow. You already attempt to foreshadow the mother's death, but it still doesn't make any sense. There is no progression of emotion or character on the part of the mom, and even though it is a diary, I would think that a young child would still be able to notice increased sadness/depression/silence. Some things are also hard to understand: Is Dad sending letters back, or not? What is Mom doing in the meantime? You need to seriously plan what you want to portray and then portray it, since it seems like you're purposefully leaving out details, but you're leaving out a bit too much. I look forward to seeing an improved version.
Also, the font is hard to read in terms of distinguishing italics, and it's a bit large. I suggest adjusting it.
