Very nice job on the BG but the extraction needs some work. But this is a nice concept.

I feel like you could have done more to give this wallpaper a little more depth and a little more perspective, just because you can see that there is space between the three godesses but there doesn't seem to be space between them and the backround...They seem to be sitting in front of their enviroment instead of being a part of it. Just adding some floating petals or mist in front of the girls and between them would have created a much tighter looking image that would have made them look like they belonged in their enviroment.

I could have done without the slight blur in the lower right hand corner, the image would look stronger without it. As for the trees, I would suggest depicting more of the trunks than the canopy, since the flowers to the right suggest to me that the trio are close to the ground and not high in the air.
