I definitely like this one! What works here is the short one word lines, it goes with the topic of the poem, and it just works. I don't know how else to describe it! Well, good work!

You've chosen the right words and it effectively brings out the feelings of Auschwitz.

Le bon travail!

Inconcievability. This is very true, but it does not create as haunting an image, I think, because of the nature of the "stem and leaf" poem. I like your word choice.
