Fireworks Brushes

Silly to ask, I suppose but I'd love to use these, and I'm still learning. How do I color them the way you did in the original? Or similar to give it a realistic effect?

thank you very much, I took it :З

Thank you!

Thank you very much for sharing.

How do you download it? I feel like a complete idiot saying this, I tried using the download button but it just crashes ;_;

Thank you!
