The best photoshoot is the one that you like.
So figure out what you want in your head first and then go for the choice of the photographer. It is really hard to choose the best one but it is also not that bad.
So what kind of photos do you want? Do you want them with some filter or you want them to look moderm? It is up to you.
If you want you can leave the photographer to improvise and then choose between different pictures.
It is better to leave it like that and make some slight corrections of the surroundings or the landscape that you want to be present on. So go ahead speak with the guy and find the best one for you.
