If you're going to make Supes and Wondy a couple, make them in their early 30s, give Diana her autonomy and make it look like they enjoy each other. This is a hot illustration (despite the bent back). The new 52 Supes/Wondy are not hot.
I can see the credit on this picture, but I can't read it well enough to track down the original source. A reverse image search doesn't help. Can anyone else help?
