Fill flash wedding roughies

Hi all.
Like anyone photographer, I have the ingrain desire to only show my most favourable or signature work. Shots like these images from Saturday (http://www.users.bigpond.net.au/pade/1.jpg change the url and go from 1 through to 7 ) But in this case I’d rather show you the stuff that I’m working on, shots that are technically and/or composure and/or environmentally challenging.
In PP I’ve only tweaked WB in RAW->jpg conversion, resized and sharpened.
The idea with these shots is to try and get an even exposure with the shadowed foreground and sun lit background. Well that’s the idea anyway. Composure wise, I was trying to let the natural lines of the autumn trees take you into the background, along with the bank of the lake and have the B&G fill the foreground. This was taken with the S3, which gives a pleasing Velvia look to the natural colours. ISO100, 12mm @ f5.7, flash was pulled back 2/3 stops in an attempt to get some form of even light.
Same idea behind this second one, but I face some significant challenges with light hitting the face without blowing out the dress. Easy to fix in PP. ISO800, 12mm @ f4, flash was pulled back at least 1 stop, but looks to be more. Environmentally, I was lying in the dirt near the feet of the couple and I didn’t have much room to move back.
This was defiantly a first, taking a long exposure on a floating wharf. Sun was virtually gone, 2sec, f6.7 12mm ISO800 and rear sync long exposure flash with SB800. Meaning the flash fires twice, once at the beginning of the exposure and once just before the shutter closes.
In the time it took me to drop my tripod, the light was goooooone.. Similar setup at the one above, just different composition although I had to wait for a boat to pass for the wharf to stop rocking.
So if you've got a critique, that would be great. Especially if any of you have used the SB800 in fading light/non studio environment. Ultimately, I will be able to post process the shots, pull up the shadows, punch the garden colours, vignette and soft blur the exterior parameters of the image to draw the image that I’m looking for.
cheers
