Hippo Ship Hat - a.k.a. jagged for IF

The prompt for Illustration Friday this week is jagged. For some reason, I decided to draw a hippo wearing a hat with a jagged edge. The first hat was more like a crown, but it didn't look quite right, so I re-imagined the hat as a ship on the ocean (no idea where that came from, but I liked the sketch so much I finished the art). Here's a close up of the hippo hat with the jagged edge:

Seagull says, "Aye! Aye! Captain Hippo!"

Here's the full image:

Originally, the picture was a daytime scene. I think I like it better at night, but I still like the daytime version too (though my file has a white background - Blogger made it grey for some reason):

What do you think? Daytime hippos? Nighttime hippos? Or it doesn't matter, as long as you can get a snazzy hippo ship hat too?
