I watch you twist old
newspapers, clip twigs,
unroll vines, pile them into
a shape that will burn,
The way you worded this a little confusing. Perhaps instead:
"I watch you twist old newspapers,
unroll vines and clip twigs,
then pile them into
a shape that will burn"
And a shape that will burn is a powerful image, too, by the way.
spotlight our faces, keep our hands,
(we'll do the rest) warm, when the sun is down.
I lean out the basement door
Spotlight our faces is abrupt and a little difficult to understand. Maybe "the fire spotlights our faces..."?
The "we'll do the rest" is great. Nice innuendo. Put "when the sun is down" on the next line because it is a new thought.
and watch you lay the pieces of your fire
precisely, so exact you could probably tell me now
the way the ashes will look tomorrow.
Put "precisely" on the previous line. That makes it more precise.
The last two lines are very nice.
Overall, a little tweaking and this will be a great poem. However, I don't really understand the title - change it or explain it.
