Walking in hand.
`I know it's necessary to keep it shorter, so that the syllabication stays on straight, but it sounds quite funny to me, the way it's phrased. It's like, I get what you're saying, but it just doesn't sound quite right.

I feel like there are a lot of words that could be omitted. Like in your second stanza:
First Line: "all" -- I find unnecessary, but when I continue reading over again and again, that can be debated. I think it's just because those three "a" lettered words in a row make it sound flimsy.
Second Line: "once"

entwined.
`I feel like, it should be replaced with "intertwined." but I don't know how you read it -- and it could possibly be that I just read at a different pace ... *shrugs. Look over it?

Images of her wrapped in our embrace danced through my mind,
Tears slipping as realization hit; our hearts are no longer entwined.
`I haven't finished reading through the piece, so forgive me if I'm wrong about what it actually means, but I absolutely adore these lines. The imagery is beautiful -- and it's clever, the usage of "her" because it makes me think that there's a new girl in this guy's life, and she's interfering with your love.

than why am I left alone here,
`should be "then"

Ooh, third stanza. Ending line's chosen rhyme is weak -- and I somewhat fancied that stanza. Be careful with your word choice, because that rhyme sounded forced and it dented the flow for me.

I can only hope somewhere in your heart
`I feel like there should be a "that" between hope and somewhere. For me, it'd help the words run more smoothly.

I absolutely LOVE your fourth stanza. It's the most emotional to me -- and though there is room for some editing in it, it's so ... charming. And your ending, though cliche, like most of the piece -- it worked, because despite room for improvement, it was actually a really great read.

Keep at it.
'Cause I liked it.
