Firstly, this is an English forum, if you want to type it in a foreign language, then use 2 descriptions (one of them would be English).
Your spell pack sounds illogical, it's practically impossible to associate it with any spell that is in the game. Not to mention that according to the name, it should be 1 spell, not a pack.
The image should be an actual screenshot of how the spell works in game.
Please post triggers of the consisting spells that are in the pack. Keep in mind that you should use hidden tags.
Changelog isn't necessary, however, it doesn't hurt.
Next time, check how other spells/packs are uploaded, or visit some tutorial pages.
Regards - LITHUFFIN.
Edit: You should DEFINITELY check more spells that people, who have more experience, made:
• Waits are inaccurate
• Casting unit should be replaced with triggered unit
• Name the triggers other than "Untitled Trigger 001-004"
• Upgrade the tooltip, because it's just a default thunder clap tooltip.
• I could go on and on about the flaws, please reconsider uploading such unprofessional projects here.
