Dear friend. I do not think this needs to be multi-coloured. I just think one or two alternatives with different logo and background colours may be interesting? For example, how would this pink look against a brilliant white background?
Great work. Love it!. You've shot into my top 3 thus far. A totally different angle from all other concepts I've got. Can you help me see how this would look on website, or business card and also, could you come up with a couple more colour variants?
