constructive critisicm of first project

Hi all,
I wanted to post my first project in UE4. I am looking for some constructive criticism. I think overall it looks a little flat. I was little confused on what type of lights to use inside. I have about 4 or 5 spot lights set to static. I have hdri light outside.
I was trying to get better contact shadows on the walls and floor. Something nice and soft.

Thanks for the time


你这个好像是UV没有展好吧? 我看看你的 lightingmass 的设置
