A nice idea. Looks like something you would receive if you forgot a birthday or even worse a weeding day! Nice focus and nice touch with the pink plants in the background. Just on thing - please cut the "Just A Reminder" sign evenly out, it removes focus when it is so... Aeh, uneven..
I see a touch of whimsy, tongue-in-cheek humor at play here .. and never let it be said that the world has enough of that.
There are subtle touches of a still-life shot with the out-of-focus elements in back and it has good 'soft' light throughout .. it would be an effective 'smile-worthy' inside joke between two people.
but .. I'd like to see you try your hand at higher quality images overall .. ones that have a more lasting, broader appeal ... because some of your works show that this talent is there .. but others are less than 'snapshot' quality (something that I would submit ;D )

show us a more serious reminder that 'love is the most precious thing' .. because, after all ... "THE WORLD HAS ENOUGH WHIMSY" .. ;o)
