There aren't any words in the silent instructional tutorial video, but if you watch carefully, you'll learn the exact steps necessary to create a phenomenal looking shooting star or comment with nice looking special effects that are achievable in Photoshop. First you'll select a circular region with the selection tool, then you fill it with white. Next you'll use brush settings to create a brush stroke that straight and fades over time to create the comet's tail. Then you'll use Photoshop's layer styles to add additional special effects on the tail of the comet, including the globe. Finally, you'll add a lens flare, some stars/sparkles and implement other simple tweaks to result in a great looking graphical masterpiece.
