Aesthetic

I like your choice of images, they are all clear and interesting.
I'm not sure if you need a black box behind each of your quotes, maybe consider finding a place on the image that the text could sit and still be legible. (that might mean making the text bigger or smaller to fit in those spaces)
Also be careful that you don't have a quote where there is only one word on the last line. (your first set)
If you still do want to have a black box with the quote in it, I think it is working better on the ones that the box spans the whole width of the image.
If you want to highlight one word of the quote in a color as you're doing now, maybe choose the color from the image itself. (for example in your first, blue picture, make that colored word the same blue as the background.
Consider having a larger size shift between the font for the quote and the font for who said it.

You've established a strong use of foreground/background. The images are clearly background.
Accomodates the shift in browser size well.
