LETTERS OF LOVE

There are letters of love
written across the sky
as I think of you.

If only I could think
of the words to express them.
Shadows of words
shaded in the blues
of the sky,
how do I find
the way to express them.
"You are so beautiful."
That is the best I can do.

Last line was originally "That is all I can do."
I wanted to change the second "think", because I did not like it, and it might not even have been the original word (I could not read what the original word was).
I have mixed feelings about the word express in there twice, I like it in both places, and also like the repetition of it, recalling the earlier express, but have mixed feelings about it.
Was originally one stanza (no gap).
