White Balance Setting

How to adjust the right white balance setting? I always use AWB but the below few shots I experimented with other setting but I am not sure if it was set correctly.

Indoor
Shot #1 - Using "Shade" setting


Shot #2 - Using AWB


Which shot supposed to be the correct WB?

Shot #3 - Using "Shade" setting


Shot #4 - Using AWB

Again, which shot supposed to be the correct WB?

Flower – under a semi-transparent roof. Which one of the below is more natural and nicer?

Shot #5 - Using "Shade" setting

Shot #6 - Edited the WB using Photoshop. The above was the original shot using “shade” setting.

Comments are greatly appreciated.
