Unhappy with our engagement photos. How to address with photographer so we can have a better result for the wedding?

EDIT: added some example photos in comments.

Our engagement photos were free as part of our wedding package. Our photographer said that it was mostly intended as a way to get comfortable with each other before the wedding. He was easygoing during the shoot. He didn’t give a ton of posing direction, but I decided that’s okay because we want mostly candid/action photos anyway. I also told him that we wanted a lot of green in our photos, but he spent over half the allotted time of our shoot in an area of the park that is very modern and all gray concrete. I would say about 75% of our pictures have absolutely no greenery. I suppose I should’ve spoken up about it in the moment, but I decided to trust his artistic direction.

We also got our photos back literally less than 24 hours later. I was excited about the quick turnaround and then quickly realized that the reason the turnaround was quick was because he put in absolutely zero effort with editing. We are an interracial couple and part of the reason we picked this photographer is that his portfolio shows good history with highly contrasting skin tones. But in our photos, the lighting and color balance is incredibly inconsistent. In some, my brownish-blond hair somehow looks pink. In others, my fiancée’s dark skin looks gray. It seems like he probably used editing presets.

There are also little details that he didn’t notice. Like a piece of my hair going the wrong direction from my part. Or my dress sleeve being flipped inside out for several photos. At the wedding, I’ll have my bridesmaids and mom on the lookout for details like that, since I know I can’t trust him to correct them in the moment.

I’m really frustrated because his work on his website and instagram is beautiful. But these photos are just…. Not good. I’m not sure what I need to say to him other than “can you please do a better job than this?”
