#72 The "Knot you have illustrated has some real strength about it, I think the black center and graph detract form the clarity and while the font is contemporary I wondering if a more elegant font would cut through
#105 Suke interesting approach, I'm struggling at the moment to get a creative link to something that is a little nebulas. Your approach with #103 & #104 looked sophisticated I think the "Knot" is strong enough with out the "CM" in the centre but using the colour selection similar to #72 that then ties in the creative element of colour
