The actual one was double the size. Well. 6000 by 6000 pixels. xD
So I found the contest just today and though "Wow, I need to enter it!" and created the best piece of digital art I have ever made.
As you may notice, I suck at water. xD
The sun is the circle, the water drops/part od the fin is one of the weird lines and the dorsal fin is the other weird line. They do match up exactly!
I do really like this. I might go back in the future to touch it up and make it better, but I'm really please with the outcome. TBH to start with I only drew it as a sort of joke to see if I could get a killer whale out of it! xD
