I like it a lot Jean, very nice color contrast and shapes I think it needs just a little anticlockwise rotation.
It is actually Yellow and Blue as the RGB is 45-56-80 but do understand the conceptualization.
It is not a rotation issue as much as it is a slight need for a bit of distortion control. I just used PS's Edit/Transform/Distort and pulled the upper right box a tad bit up as you can see in the image edit. I used two guides for vertical and horizontal alignment.
looks like a successful edit to me.
The yellow and black is wonderful in it's tonality. I like how you cozied up to the facade of the building Jean!
