Did you mean to enter this in the complementary colors challenge? If you did, you missed the mark.

If you intended it for the "Your corner of the world" challenge (which I suspect), I'd probably give it a 4 or maybe a 5, because, despite it's title, it appears to be mostly a picture of a sky, one with nice texture, granted, but a sky with nice texture could be found anywhere.

Comment by HVGB_photos:
Complementary colours are pairs of colours that contrast strongly when compared to each other.
Black and white are neutrals and not colours at all, and therefore they cannot be complementary colours... white shows the presence of light, and black shows the absence of light. Black and white areas next to each other do demonstrate high contrast, but high contrast gives a different visual effect than complementary colours do in a picture.

Your image demonstrates a duotone effect rather than the effect of complementary colours.

Check some of the forum discussions on complementary colours for suggestions on using colour for contrast.
