Based on the sky, it looks like you took this at sunset. This was a tough shot to take, and I presume you had no external flash.
Vision: 4 (above average)
For someone who isn't a wedding photographer, you had foresight in wanting to take this photo at sunset.
The bride herself has a rather interesting bridal gown.
Originality: 3 (average)
This style and pose are seen often in destination wedding photos, so it is not breaking new ground. But, there isn't anything wrong with doing this type of photo either. Some wedding photographers would say it is a "bread and butter" photo, something you have to do at these destination weddings.
Technique: 3 (average)
The bride is not well-exposed, so it greatly weakens the impact of the photo. Basically, the bride blends into the background. f1.4 is a good aperture, but 1/320 is probably too fast of a shutter speed, preventing you from letting more ambient light into the camera. Yes, going slower risks some camera shake, but you have to practice holding still.
If you had an external flash, you could make the ambient exposure darker and let the external flash be the primary source of light. In this case, you can shoot at a lower shutter speed, because the flash will "freeze" the bride, greatly reducing any camera blur. (There may be camera blur at the edges where the bride meets the background, but you would have to zoom at 100%. And, no photographer gives their client the 100% zoomed photo.)
Impact: 2 (below average)
Because the bride is not well-exposed or separated from the background, the photo is robbed of a lot of impact. In short, this photo needs more light from somewhere.
I just remembered one other suggestion in case you are in this situation again and have no external flash.
Pose the bride so her face is pointing somewhere in the direction of the setting sun. That way, her face will be illuminated by the sun going down in the horizon. In this photo, the bride is facing away from the setting sun, so you lose the light from the sun.
The bride doesn't necessarily have to face the setting sun directly; she just needs enough of the setting sunlight to brighten her face. Your camera meter should give you a slightly better reading.
In conclusion, always think about the direction of light falling on the subject, whether that is an external flash, the sun itself, or light bouncing off a wall or reflector.
