This one feels less cluttered, but I don't really like the lines from the central area... if the yellow one could somehow start below (for instance, putting the title at the bottom of the stack) I think it would look better.
maybe have the lines feeding in from the different outer areas spread out into a suggestion of a box around your contact details? Not a full box but just a few millimetres either side of the lines. Do you know what I mean? I think that could look quite effective.
EXCELLENT idea, btw, clear, powerful and original, hop it gets you lots of jobs!
