There doesn't appear to be a widely known public figure or specific content trend associated with the name "Mahima Tanni" in relation to Frozen or a "zip" file.
Is it based on the Disney movie, a specific aesthetic (ice/snow), or a frozen-in-time concept?

Is she a character you've created, an artist, or a cosplayer?
