Work in Progress - Tea Party

I have a fantastic job for a fantastic company, who lets me do creative things in between the daily work we do. Here's an image I'm working on:

I'm combining my primary craft, photography, with what I studied in college, illustration. The company's product is the table and chairs, so I had the idea to illustrate an imaginative tea party using the product. So far so fun!

What are your suggestions to make this more successful?
