Now and Then

[AlstonTowers]

Now and then, I see your face
in a memory, in a picture.
I wonder how it looks today [Don't think you need 'today' here as it is implied with 'age' and throughout the rest of the poem that time has passed.]
under the shade of age. [Generally do just like these lines.]
Once in a while,
since i don't think so much about you [Great interjection: 'I don't think so much about you' is very simple but perfectly adequate.]
anymore,
I believe time has done away
with its beauty;

That your eyes don't shine, [Basically I am just cutting out words that I believe are superfluous or make the image more simple and thus more striking.]
and your lips have thinned,
and your skin sags.

Other times 
I imagine you dignified,
wearing the crown of experience---
gazing neither behind or ahead,
but staring squarely at the moment.
You watch as it passes,
[i]taking with it another  [Taking another, stealing another...I'm just not sure about 'taking with it...another', feel like there needs to be a pause between 'with it' and 'another'.]
fine detail of your sunken face...
Another detail,
like all those gone lost  [All those gone lost? Not sure. Maybe just all those lost.]
somewhere in my mind.

All together a good poem. With just a little amplification of the images you will have yourself a striking poem. Green = good.
