I've decided to dust off the ol' tablet and become reacquainted with photoshop's drawing tools.
The scene is from "Harry Potter and the Methods of Rationality," which is a fan-fiction featuring a rationalist!Harry... I won't spoil what exactly is happening in this chapter (It's from The Stanford Prison Experiment, Part Two). You can read the book here: [link]
The storm is quite a bit less intense in my drawing than it should be... I might try to do this scene again if I feel my skills have improved.
Ooh, I really like the texture to the whole thing. You're right, the storm doesn't look very intense, but it looks pretty oppressive and I think that works even better here Great job!
