Ice diving! Thanks, but no thanks!
I am not a claustrophobic person, but when I am watching a movie and there is one of these scenes when someone falls in a frozen lake I'd rather not see. It must be the most exasperating experience of all.

That being said, the photographs you were able to produce are just amazing. You make ice diving look attractive, enticing. Just beautiful shots. They were already impressive without the acroyoga :)
You stay safe
