I'm a fan of doing things differently, thats awesome. There are too many people who take the same old photos at weddings, slap some standard photoshop actions that they always run on their images, do some other minor adjustments, and call it a day.
I feel that all three images missed their mark as being good artistic images.
#1 I get the silhouette, but what I dont like is the boring sky. To go with something like this, I'd love to see some great clouds or other features that are appealing to the eye. There is a lack of that here, and the top left of the image is pretty white almost blown (i'm at work, so can't be 100% certain due to crappy work monitor).
I also don't like that you chose to have her face towards the short end of the frame. While that can work in some instances, I dont find it does here as it kind of removes any balance from the image and makes me feel that everything behind her is wasted
#2 that tree on the side is really killing the image for me. Wide is good, but this one is too wide for me and that joined with the tree, make me feel like the B&G are non important. Its good to be artistic, but you need to keep in mind that the images still need to have the B&G, their day, their guests as the focus.
#3 I like this one, mainly due to the lines in the fence. Gives a nice feel to the image and I love the wood texture. The BW conversion is nice, the low contrast is interesting. The bad? Their hands dont look in focus. I don't like how you only have 3 of the hands on the fence. This might be a great shot of the rings, but they aren't easy to spot. I also dont like how you have the bouquet in this image... the stems are prominent and the flowers are cut out of the frame. What was the point in having it in the image if you aren't going to show it? I would of put the bouquet down, had the bride put her second hand on the fence, made them put their hands a bit more wrapped on the fence and zoomed in a bit more to get the rings. But the basic out of focus of the image is what kills it the most for me.
