Photoshop Stars and Sparkles
This set of fourteen photoshop brushes, feature stars of various sizes and sparkles that can be used to add highlights to other images.
I have used these sparkles on a recent design created in Photoshop. If these turn out to be popular I'll add some more to the set.
The Crop Circle photoshop Brushes set might also be of interest, featuring Vectors Shape Brushes.
