You have an attractive color scheme. I think you'll achieve the "pop" you're looking for best if you edit some of the distractions. Paint the porch supports and railing white. Or you could replace/wrap them for a sleeker look.

Remove the window boxes, potted plants, shutters, rock edging, and clean up the landscaping. Make sure there's a clear path to the front door. http://houzz.com/photos/1370445
Now for the "pop." Paint the porch chair, a large pot, or just add cushions in a color that contrasts the door - focusing all the attention on the entry. Make sure the light and house numbers go with the new look. http://houzz.com/photos/1069993
When you're ready to update the landscaping, plant most plants in large mass groupings of the same plant for a cohesive modern look. http://houzz.com/photos/5139703
