Painting The Summer (first edit)

This is my first edit so I still need all the advice you can give me. Do the prose flow as well as they can or is there still any excess wording? Is there anything you weren't clear about and that you'd like me to explain further? Are the characters well-drawn and believable, and does their dialogue sound natural? Give it to me straight and thank you so much for all the feedback you've given me so far. It's been invaluable.
