Hey, David. Great to see you in Poetic Forms again! I took the liberty of re-formatting your poem for you, moving the lines back to flush-left and then using the centering icon above. If you have trouble figuring that out, let me know. Just left-click your mouse to scan/highlight the desired section and then click the 5th icon from the right on the top.
As to your lanturn attempt, I'd say that you're right on track, except line 4... 1) I don't think you want to end with a definite article, and 2) I think you can make the line a bit more self-sufficient... one of the 'expectations' of the form...
Maybe something like this ?
leaves'
last fall
from the trees
gently reaching
ground
You might also want to consider the second paragraph of the form-description above... There is another nuance besides the 12341 that you might want to give a try to as well... but of course, one step at a time!
Looking forward to your continuing Light, Daniel 8)
