The problem with Vacuo is which way the sun is. It's presumed to be late evening, the sun is setting in the scene she's in, hence it is to the west of the image. For it to be in Vacuo, the sun would be setting behind her as the main harbour she would have arrived in from Vale is on the eastern side of the Kingdom. She would have to be looking east.

If that was case, the sun would be rising. But because the sun is on the left side of the screen rather than the right, it lends credence to the assumption that the sun is setting, which rules out that main harbour of Vacuo's which is closest to Vale and would be the main port for Blake to arrive in Vacuo in.

Therefore, by looking at the composition of the picture we can safely assume that she is looking out at a sunset, and is therefore not on a dock in Vacuo looking back east towards Vale. However, by that same logic we are able to make assumptions about her looking west, either from Mistral to Vale or from Vale to Vacuo.

Given that she was shown running around Vale at the end of V3 and had no intention of returning to Mistral, which is where the White Fang and Adam are said to be based given that Adam did say "return to Mistral" in Beginning of the End, we can presume that she is not in Mistral. For them to jump her ahead so far in terms of character development off screen, by sending her to Mistral to deal with her demons and not showing us the development through the show itself, would be extremely terrible writing. As in, so terrible even Miles and Kerry should be able to see how bad an idea that is.
