do those curves need extra postage?
i love this postcard. if i had friends in sunny places, or lived in a tropical place to send this to my friends that live in terribly unsunny places, i'd use it. oh well. i feel like this would make a great poster as well.
i think your backgrounds are strongest when they're simple and solid(non-gradient or fuzzy) like this. the abstract sun adds alot of style to the mix
