Cut the black space.
The white streak is kind of random.
Text of that type needs to be closer to the focal. If you're not going to use the art form of text, then make it really close to the focal, go with the flow, and blend well.
idk, I kinda like the color scheme, in the sense that the backlight and her eyes provide great contrast between the black/white background. Though I agree that it didnt flow as well as it could have. I like it overall tho!
I didn't say I didn't like the color scheme, but I will say that I'd prefer it be straight black and white except for her eyes. That misty blue by her head is just not right. If you don't like that suggestion, try making the blue more prominent; sure it's a great contrast, but it's not prominent enough. Try to put some more emphasis on the blueness of her eyes. That would be a nice little thing that'd I'd actually be interested in seeing how you pulled it off.
