Good image author, but you need to post the original uncut photo in the SBS so we can see how you manipulated it.
EDIT: Thanks, now we can see your work.

Uncut is now up loaded.........sorry.

Really great idea but there's some room for improvement: the light casting on the boy is a bit oversaturated, specially on the right fore and upperarm.

What I see from the original photo of the boy that you even made the dark areas lighter, I think your profit is to be gained here. You can make the original photo a bit darker and use that as a blending layer over the original photo, so you make the lighter areas come out more. On top of that you could lighten the areas you want lighter a bit more.

Something else: in the high res there's a purple area over the boys thumb and the moon and the boy are transparent at some areas, these last 2 are easy fixes though

Cool idea. I admit I don't get the boy-in-outer-space thing unless this is supposed to be an ad for a sci-fi movie or something. As an alternative, I think if the boy's original hedge and tree-trunk background were retained and then augmented by the intense stars-and-Mars [or more-appropriately moon?} sky, this would be more understandably dramatic. [BTW what is the light source for the jar lid and his fingers holding it?]
