Searching for the Spark of Hope

This is for the upcoming EOY(End of Year) Anime/Manga/Cosplay Convention's Art Competition...
I don't know how i'll fare...but i'm giving it a try...

Anyways, theme is "The Spark of Hope",
So I came up with this piece.
Just want you guys to share your thoughts about this pic and how i can improve it before submitting it up to the organizers.
Felt that it was alittle bit tooo sparkly.. =x
Oh well, i don't know, what do you guys think? =x

EDIT:
Edited the wings alittle by reducing the whites and adding in alittle more detail as said by many.
About the lighting issue, i purposely wanted the wings to glow as well as i don't want the details of the wings to fade.. =x
Then again, i'd like to thank you guys for making really helpful comments and critiques. ^___^ =D
