This is a good poem, I like it alot. I probably would consider making it a little longer though. I get the visual you're portraying with the bare trees and surrounding ashes, a very dreaded, empty place. Overall it's very well written, good job :)
Yeah, its short, but with good pictures and motiv. The emotions behind the piece stands strong. I felt like the end, on the second verse, it came a bit abrubt. Thats all. Perhaps if it had rhymed, or you had had a shorter verse of perhaps only two lines afterwards, that it would be better.
But all in all, a very good poem. Write more, enjoy!
Criticisms: The poem leaves the reader hanging - what happens? Does the character die or is he/she rescued somehow?
I get the feeling that the them of the poem is one of panic - a deer in the headlights type deal. IF this is correct, then you might want to consider tweeking the language a bit. For example:
"Not sure of what to do" could be revised to "unable to think, instinct swarms in but helps nothing," or something a little more intense. "Not sure of what to do" is something I feel at the DMV - not when I about to be fried.
In other words, the language doesn't fit the emotion of the situation.
Also, punctuation and spelling should be checked (of course I probably shouldn't throw stones)
Overall, the piece shows potential as a good snapshot for panic - a forest fire raging towards the character and an impending, horrible death.
If I were you, I'd try this again as it does show the setting quite well.
