Shooting same city--again
These were my thoughts exactly when i was reading the intial post.
Alternatively, if you are happy with your photos, why not go explore a bit more of the city or area. I don't know how big or small the city you are going to is, but I do know that no matter what city you go to, you can always see it from a different perspective. Maybe this time around take the pictues from a differnt angle or point of view. I'm sure you can think of something really creative and just go with it. A lot of time I don't know what I want to shoot until I'm looking at it and then the creativity kicks in and I just go with it.
Hope you get what you want from the trip.
