The background of the first one is better, simply because the grass on the second one looks like it's growing out of control--like whomever is caring for it is doing a poor job.
But everything else about the second one is better. I like the water droplets, I like the lack of the lime-green accents (they're too busy), I like the website on the bottom, etc.
Any chance you can take the background picture of the first one, and everything else from the second one, and merge them together?
You may want to change the font, regardless of which background you use. The characters are narrow enough and the background is busy enough that it becomes hard to read, and the characters don't really "pop". I'd consider something with the characters beind wider in general, possibly with no serif, and if there's sufficient space, maybe outlined?
(For an example of how font outlining can affect readabilty, take a look in my library at the file "Emma party invite final--big.pdf", which is a fake concert poster/invitation I put together for my daughter's upcoming rock concert-themed birthday party.)
