A land not so far away

Wow, this is pretty!

I really like your use of imagery and that you have an obvious time progression here. Nice.

There are a few suggestions I'd like to make to make this pretty little poem even better.

Her childhood
Consists of cloudy grey skies and muted rain

Even though the line is going to be rather long, I'd combine these two lines. The first line is short and stumpy and doesn't do anything for the reader. I want the first line to draw me in and make me want to read more. I love the image of "muted rain." As for cloudy grey skies, take out either cloudy or grey because both is overkill. Perhaps even find another adjective that is similar to the way you used "muted." Also, put a comma at the end of this line since you continue the contents of her childhood in the next line.

At the end of the third line there needs to be some kind of punctuation. You barely punctuate this poem at all, and it needs some in order to improve the flow. I'll address more of this issue later.

Days that were spent
In two cent candies and cheap plastic toys

Like the first two lines, I suggest you combine these two lines and cut down on the second line of the pairing a little bit. I like "two cent candies," but "cheap plastic toys" has too many adjectives on the front of that thing. You could try "brittle" toys or "tinfoil" (because tinfoil calls to mind tin toys, but has the fragility of foil), or some other creative adjective. Just try to stay away from the cheap plastic there. You could even say "dime store" though that is rather similar to "two cent."

Until one day, on a warm August day

I have several things to suggest about this line. 1. don't italicize it. It draws attention to the fact that it is repeated, and repetition should be natural and unnoticed. 2. don't use the same word twice in the same line. This line needs rewording. I thought of a great substitute: Until the August day. It adds a sense of importance to that day because I use "the" instead of "a," and it just sounds lovely rolling off of your tongue. Use that, and it will be so lovely (personal preference, you know)

The wind howled and she soared high
High above the coral clouds

Only one high is necessary. Using two makes you seem like you're trying too hard.

I love "coral clouds." FABULOUS image.

With the confidence of a massive continent

Hot dang, that's a good line.

In the line following that lovely line, remove "away" because it clutters up the line.

I don't know what you meant by "temperatural" weather, but that's not a word.

Days that were spent
Under bird calls and crystalline blue sky

I'm going to make this suggestion one last time: combine these two lines. Also, remove "blue."

The sweet taste of childhood love

Here is the one place I wanted more description. There are so many different kinds of sweet that I want to know the exact sweetness of childhood. I'd like to think it tastes of strawberries. I might write it like this: "The strawberry sweetness of childhood love."

NOTES ON FORMATTING AND PUNCTUATION:
On this site, to keep a single spaced format (which you should always do for poetry) you need to hit shift when you enter down to a new line.

Now on to punctuation.
You simply need more in your poem, dear. Here is how I would punctuate it. Feel free to change any of it (though I don't condone changing it to make it grammatically INcorrect. Don't do that.).

Her childhood
Consists of cloudy grey skies and muted rain,
Of humid winds and polluted coughs,
Days that were spent
In two cent candies and cheap plastic toys.
Until one day, on a warm August day
The wind howled and she soared
High above the coral clouds
With the confidence of a massive continent.
Breaking away her past into silvers of dream,
It lead her to a land
Of temperatural weather and strange dialect,
Of fiery heat and frosted winters,
Days that were spent
Under bird calls and crystalline blue sky.
Until one day, on a warm August day
She tasted in her aging years
The sweet taste of childhood love
As she remembered
A land not so far away.

I hope that this proves helpful to you. If you have questions, don't be shy! Private message me. Happy writing!
