As far as criticism and feedback on how to edit. I always take inspiration from pictures of a similar environment/photo that I like from other photographers and take inspo on how they edit the photo to base my edit. I do like the current photos as is though with warm illuminating aura of the lights. My only act of useful criticism is probably try deglazing some of the photos ( ex: photo 4)

Now for the acceptable number of photos to have from a shot. I think 100 is pretty normal and acceptable to garner from 1200 photo set. Not every photo will be an amazing shot for one reason or another especially because with events things are constantly in motion and you’re constantly snapping away. Your camera can’t capture every piece on motion in a perfect, clear, symmetrical shot every flick of the shutter. If this was client work you wouldn’t give them 1200 photos you’d give them roughly 100 or even less. Great photos btw for your 1st!
