An excellent way for the characters to meet. Emily's precocious dialogue adds a lot to her character, and Ruth's lines are very natural also. I like the sense of childlike enthusiasm you get from including so much movement and play.

I realized after my last comment that a few of the other words you use to refer to characters are also good. Stick with these standard usages:
-the boy -the girl -the man -the woman -the boys (etc.--plurals of all of these) -he -she -they -[Name]
And please try to stay away from these arrestingly uncommon ones:
-the brunette -the female -the male -(plurals of all of these)

That's a lovely bit at the end of this chapter where Mr. Barrie realizes he has found new inspiration!

This is a good beginning. I like that you plunge straight in, especially when you introduce Ruth and Emily, letting the reader discover the characters without getting bogged down in backstory. I also appreciate how you state the facts of Mr. Barrie's depression (no good ideas, no visits to Neverland) and let them speak, without including a lot of angsty interior monologue (no "oh, I am so sad" stuff).

One small adjustment that I would suggest--avoid referring to characters as "the brunette" or "the males." You do not need to find a different way to tag the character each time; it is fine to keep saying "James," "they," "she," etc. These standard tags are so common in narratives that readers don't even notice them anymore and can keep reading smoothly. When you use an uncommon reference ("the blond"), it forces the reader to pay attention and break the flow of reading. This is the same phenomenon that lets authors use "he said" over and over again--readers don't even notice this repetition, but we are forced to notice if the author writes something very unusual such as "he enthused."

It would also help to look back over the text a few times--occasionally you seem to leave words out by accident.

Overall, this story promises to keep the reader's attention! Keep it up!

That was a really good story! Please update soon!

Very nice job!
