The Internet removes all subtlety and makes all criticism cruelty, so please know that I am genuinely commenting.

1. I am not sure why the tiger is crying, and it seems to be written so the poem isn't mysterious.

2. The color scheme and the solitary/companion tone all shift too much.

3. The poem is intent on rhyme, instead of expression.

I'd recommend heading to the poetry section of your local bookshop and flipping through books by Sylvia Plath, John Ashbery and Hart Crane to get a taste for where American poetry has gone in the past century.

This isn't meant to be snide at all. You have a range of vocabulary and a sense of rhythm.

Oh Thanks. I'll check them out.
