I too agonise over colour! I sometimes feel I spend too much time, rather than 'going with the flow'.
That said, whilst I love your blues, something about the yellow Nos. 6 & 7 jar with me. I can't make up my mind whether my eye is being drawn to 6 because of the more pronounced print or I notice it when my eye is drawn to the strong No. 7 (told you I can't make up my mind, lol).
However, if you've taken a black and white photo and are happy, then that's all that matters.
Happy quilting
