Would English SE be a good place to post a paragraph or two paragraphs of my writing for review?
You can ask explicit questions about a short sentence of yours, if you highlight the parts of it that you want input on. For example, the following is on-topic:
I wrote to a coworker: “if I was in your place, I would refrain from talking to him until he apologizes”. I wonder if was is the correct verb to put here, and if there is a more concise way of saying “refrain from talking to him”. Can you help me?
Asking for help without saying what you need help with is off-topic. General proofreading is off-topic, and advice regarding style, long descriptions, and such should go to Writers.
