I love Vero, Done!

 I decided to stitch the body of the dolphin and the lighter green of the "green" in the diagonal mosaic.  I like the texture it adds.  I also did the palm tree trunks in the chain stitch to make them look nice and "barky".  

 When I first finished stitching, I noticed that the shading on my grapefruits was too dark and noticeable.  See this photograph.

 So I picked out the dark shading and put in the lighter pink from the dolphin.  I think it looks much more natural.
