This wasn't really my cup of tea-
at times it seemed a tad cliche and forced
and then at other times it was perfect.
Example-
It opened with a nice metaphor,
eyes like a window, rain=tears etc.
But then the 2nd and 3rd stanza brought it down,
until you hit the 4th stanza and again its nicely done!
Maybe try revise over and pick out the best bits,
then rewrite/rephrase the parts which seem to drag the poem down.
