I can't speak for Saimon (obviously) but when I read your original post, I felt that it needed clearer formatting - and I suspect that's what Saimon meant too. Breaks between paragraphs, a new line when a new person speaks etc etc, rather than just a solid block of text.
Also, I wouldn't really use a phrase like this to describe something,
"Suddenly, a haze of red things went out of the box"
Using an expression like "red things" is far too vague, it doesn't show us anything. Whatever the image you'd had in mind, describe it to us
