Love the sketch. It proves that one does not need vibrant or passionate colors to display the loveliness of a scene such as this. Setting up a long shot for the couple, along with the space, emphasizes how they seem to be the only people in the world, the only ones meant for each other. And all it takes is a glance and a smile, a hold of the hands, to prove their deep affection.
A comic! Splendid. With that brief background of your two characters, I am enticed; thus, I shall look forward to your comic. Will you be posting that here, or on your site?
