So I started this dawing as a simple doodle, but then ended up with this.

First I started with just a gradient, that turned into a ocean, which led to made me adding clouds. I then wanted a sunset backdrop.
For the longest time I couldn't decide on the forground, until ultimately I got the idea to do a whale

Side Note: Sorry for the red sigment in the video, I was going to do something with that, but then i quit and forgot why.
