This artist revises her artworks frequently. In the meantime, she revised this artwork again, but I'm not going to reupload this right now.

I still can't tell, but I'll take your word for it

Well, for once, the first one to be uploaded had deeper tones and more shadow, you can easily see that comparing the 2.
The rest you just need to look a little more into the details.
