I belive you can pull more out of it.
1 - The first camera view you posted looked better.
2 - It is lacking some enviroment around the building
3 - Material are lacking detail, dirt, textures.
4 - Also there are a lot of detail missing on the models, There are always some separation between the mall it self and parking lanes, also there are always arrows showing you derection on the lanes, (i have attached image as a good refference of what is going on on the parking)
