Explosion wouldn't be symmetrical or so opaque, otherwise not bad.

I agree with CMYK46 on the need for 'explosion' asymmetry in order to appear more realistic. I also think some (perhaps around two-thirds) of the foreground grass needs crisp edges in order to create a feeling of depth.

IMHO this would improve by replacing the "stones" with a pic of turquoise or something...

Interesting idea, but shadows on the wearer's neck would make it seem more realistic.

CMYK46 - Think I'm made of money??? and DanLundberg - there are shadows on her neck ....Maybe you mean at the bottom of the image?? Comments are appreciated, thank you.:-
