I am rarely creative during a shoot - my mind blanks and I fall back on things I have done a hundred times already - but occasionally before or after a shoot I have bursts of inspiration where I can visualize various posing positions.
During an actual wedding...I tend to try to avoid certain environmental features and unwanted stuff, and I may adjust my position to use someone's body to block those things...I often watch out for distorting faces/arms with wide lenses, look out for stray hairs on the face or back fat or fat arms, catch the subject smiling or otherwise engaged in some way that is interesting, try to capture multiple things happening at once or context in a photo if possible. Sometimes I look for frames, rarely for things to shoot through. I often try to isolate subjects while still establishing their connection to someone/something else nearby. For formal photos I do occasionally try to create head-triangles. I would like to use environment better for formals, but I don't have the knowledge to create effective compositions for unique body positioning.
Posing times...I try to look out for fat, double chins, stray hairs again, and what angles look the most aesthetically pleasing about the bride in my opinion. I know just a few tricks at this point to reduce some flaws. My poses are still contrived and boring and I lack enough understanding of proper positioning of various extremities and body posture to accurately visualize any specific pose. However, as far as scenery goes, I often have an idea of how I want to use the environment before I actually tell the subjects how I want them to pose/etc...I will try several framings of the same shot, usually finding one I like better than the others.
