This is wonderful. Many people go ahead and work from the cliché, "I'll give you the keys to my heart." Some are effective with how they portray it, and others don't really grasp it at all. I think you were one of the people who grasped it and put yourself out there in an effective manor. Since this phrase is so commonly used, I like your almost 1700-1800s theme. The calligraphy, ink, old old keys, and glasses are so perfect with this. The warmth in the photo also makes it seem aged. It's like they weren't just giving their lover their heart, but a love letter to go with it.
Thank you VERY much! I wish I could say I put that much thought into it, but I'll be honest and tell you I didn't... I just thought it all looked cool together!
