Try to check the background to avoid people in bright colours standing out sore thumb style.
Where you have exotic animals things like oak trees in the frame tend to suggest zoo. This type of thing can be minimised with a wide aperture and a long lens, but make sure you enough depth of field for the subject.
If you use a polarizer to shoot through glass remember not to have the lens parallel to the window, 30-40 degrees works best.
Lastly enjoy the day out.
