The Whacky Whale Water skied on Wild Waves

I really struggled with the wave in this painting. Most of it is actually cut off - poor planning on my part. I think I need to scrape away paint to show more white. Does it even look like a wave? I'm not convinced.

Do you know how many types of whale there are? And they all look so different from each other. It was tough deciding which kind to include in this painting, but ultimately decided on a blue whale.
