The lighting on the face is inconsistent with the background you are using. You might try selecting the face, and going to Image>Adjustments>Selective Color>Whites, and try bringing down the white tones in the face to better match the rest of the head and neck...

thanks and corrected it.

The face still is noticeably lighter, with the sun shining DOWN from behind her.
Her hair and shoulders show NO lighting on them at all, while you have a VERY strong shadow coming off of the bottom of her dress, although the dress shows no corresponding shading away from the sun light source.

I'm sorry, but whatever corrections you've made have not helped the inconsistencies between the contest source, the woman's body and dress, and the background you've selected...In competitions like this, such inconsistencies will probably have a negative effect on your score.

Nice idea with thinking outside the box with the source, author!

Nice concept author, GL!
