Once again a noob has appeared. All went silent. Then, at the far end of the thread someone started laughing. Silently at first, then as seconds passed louder and louder. Soon everyone in the thread was laughing. Through the cacophonous sounds a voice cried: "U NOOOB!"
Anyway, I experimented with the brush tool and the levels/curves, to create this background.
Ignore the void on the left side, as it's meant to be filled with a ship render or something in the final signature version.
