Hmm to me, it seems like the lighting is too harsh which resulted in flat colours.
A simple way is to change a bit of contrast and brightness, and up the saturation. Some simple programmes will do the job, or use photoshop like what others have suggested.
Also try not to shoot under bright and direct sunlight, especially in the afternoons.
Anyway just curious, I wonder which spot did TS focus because the pics don't look sharp even at f/9.0.
