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.

While I find this an interseting setup and concept, for me, it doesn't meet the challenge of complimentary colors and I have given it a low score. The composition isn't bad, but the light is a bit bright and I find the fingers dristracting. Maybe a bit less yellow color overall would help? Like I said though, an interesting concept - shows creativity and imagination.
