Error Level Analysis (ELA) permits identifying areas within an image that are at different compression levels. With JPEG images, the entire picture should be at roughly the same level. If a section of the image is at a significantly different error level, then it likely indicates a digital modification.
I dont know anything about photoshop or image compression, it sounds like you do, so to play devils advocate I'll ask this. Is it possible that it comes up that way because she's the only thing in focus and everything else is blurry?

Never mind, I got it. You have to use the image from twitter. The closer to the original the better.
