Add into archive the cropped version, I think that she looks good too

Very unique entry! However those bright and discordant colors present two issues for being used as a wallpaper:
- When the desktop abruptly comes into view after being covered up (e.g. when minimizing or closing a maximized window), a wallpaper like this with very bright colors and abrupt visual transitions can seem a bit eyeball-searing.
- Desktop icons can be a bit difficult to pick out amongst a very busy pattern like this, and their labels may not be very legible.

I would recommend keeping these two conditions in mind and reducing the attention-getting-ness a bit.

Much better! I like the direction this is going in.

Any suggestions for improvement?

just an idea

I like that latest one even better! I'm seeing a good progression here. Next I might recommend taking inspiration from the Breeze color palette (https://hig.kde.org/style/color/default.html) and using a few more of the darker colors too.

Color palette and darker colors for this work or another?

Can triangularity be replaced for the new version?
