Your poem began a little off, and I didn't completely understand where it was going. The flow was choppy but when it came to the third stanza it picked up, the flow was added and a rhyme scheme sort of popped in. Or perhaps that's just me?

"A step, then two
A whimper than none.
From cold to warm,
From Life to Death. "

^Your ending had a good idea to it, but it wasn't absolutely perfect. 4/5
