Very interesting. I want to see what else is going to happen.

Since this is only the first chapter, it's difficult for me to comment on the story thus far, but it does look like character relationships and plot elements are being steadily established. You write very competently for the most part, and I particularly like the detail of certain dialogue exchanges (such as when one of the girls was giving advice on different aspects of the other's drawing). One thing I would recommend: try to find new ways to distinguish the two girls early on. I found myself getting the two of them confused with each other. Suggestions would include a certain physical quality, a favored style or article of clothing, or a unique demeanor that each of them might have that could be referred to in order to develop a clearer mental picture.I wish you all luck and success in completing this story.
