These are gorgeous.. I want.. I know this may not be feasible, but if these were made into buttons it'd be really cute if they were actually heart shaped as opposed to the traditional circle shape - heart shaped buttons would be really unique and I would personally stalk you down to buy a set!
I thought it might be a bit pricey - but don't worry, one day your creations will be world famous & you'll be rolling in enough dough to do it then (with all the good karma you're generating by putting smiles on people's faces with your art, how could it not happen?!)
No I am not even remotely biased. How dare anyone think that.
