Here's what I've got so far, starting with watermelon. I mostly like how the flowers came out.

Next, limes. These took me a long time to clean up in Photoshop. How do you manage to not have many stray pixels?

Last, and my favorite so far... tomatoes!

I'm also wondering how when you use so much water, you avoid getting hard lines. 

Another excellent class! I hope you'll make another new class soon.
