Your lighting seem very harsh. A cause might be using unmodified speedlights aimed directly into the scene, see photo 4. Photo 3 appears to be a touch out of focus and the the general feel is rather snapshot like. Are the images you present here the best of the bunch, or are you asking for advice concerning the missed shots? Were you shooting this wedding for a friend or family member as a freebie?
This seems pretty harsh critique, but if this is representative of your wedding work you still have a fair ways to go. Weddings are special for the celebrants and as the hired photographer you need to be at the top of your game in order to deliver on the implied promise of a good product.
I've been assisting a wedding photographer since April, and building my portfolio. Every wedding, I try something new, and these are the first with off-camera lighting. I know the shots aren't perfect, but I'm happy with them. #3 is OOF, but it's one of those instances where the camera didn't focus perfectly, but I liked it too much to throw it away.
It's not harsh critique, it's just directionless insults. I'm not sure how your words are supposed to help me improve. They really just seem like condescending insults.
It's not "harsh critique" it's just
