ok this was my 1st trial at changing background. I changes the sateration to match the sunset as much as i could.

you may want to blur the background a bit to give the illusion of actual depth. I wonder if using the lighting effects in ps may make it a bit more convincing that the lighting on your subject is from a strobe or two.

The things I notice are:

- The shadows don't match the light direction.

- The clouds are visable on her hair on the left side of her head.

- The horizon is too low for the angle of the bike.

The horizon is the biggie with this imo

Ideally, you need another sunset shot, because this one is from the perspective of the camera pointing somewhat upward, while the bike shot is taken from just above the subject pointing downward - match the angle and most of the other problems resolve themselves, or are not prominent enough to be noticeable. Cool idea though!
