I made two different versions and ended up choosing the more simple option (on the left). The illustration was also part of the Valentine's day Illustration Rally and got featured with a selection of other sweetly illustrated Valentine's greetings.
Since I started roaming about the heart-shaped boxes of chocolate, I would like to add that even if I think they are mushy, I don't have anything against them (or their contents). In fact, I don't think chocolate can ever be a bad idea, no matter what kind of package it came in. Actually, my boyfriend has also surprised me with chocolate once by leaving a collection of M&M's and Kinder Buenos behind my door. They were wrapped inside a plastic bag with an anonymous note saying "don't eat them all at once" (which I of course did). I'm sure they couldn't have tasted any better even if they came in a fancy box.
