Thanks all for feedback!

Yes, of course, we are at a very early stage of the work on the our wallpapers.
This is not the final version.

I concentrated on two aspects:
1. Fireworks as an idea.
2. Abstraction for a unique idea.

This is the first very simple version, and it has many problems.
I want to try to continue this work by changing this variant (or other) based on your opinions and ideas.

Alexander.
