My version is very similar, using the red and white color scheme, hearts and envelopes.
I cut two "Sending" sentiments, one of the red cardstock used for the scalloped heart and one of shimmer silver cardstock. I thought using them with a shadow effect stood out more than either of them alone. The card front is popped up off the card base, as well as the red banner and "Sen" of "Sending" (to keep it flush with the rest of "Sending"). Otherwise the profile is lower so I can send it easily through the mail.
