None of the color edits thus far in my opinion have significantly helped the piece. They have given it different directions, but they have not proved them to be more valid than the slightly more washed-out original with the red leaves. That also happens to capture a pretty nice ambience. Not to discredit the work of those that are helping, but I don't see them being very successful here. If anything I'd add a bit of saturation in the bg tiles of the original mockup (yes, therefore moving it closer to the foreground, I see no problem with that. Value range differentiates the layers clearly in my view) and call it done. Very Henk Nieborg'ish, very nice mockup.
