I really like this but the colours on each letter might be just a bit too much. Id prefer with such a playful logo to tone down the colour variety or less playful but colour still there. My linked in profile is http://www.linkedin.com/profile/view?id=38545663&trk=tab_pro
A subtle reference to medical is fine, but it is important that I dont confuse anyone thinking that I am offerering any sort of clinical or medical services. What I offer is a business consultancy service to businesses that sell product into the medical arena. Some of the businesses I deal with are ConvaTec, CareFusion, Multigate, ITL etc. these are the types of companies that I am selling my services to so my logo needs to suit them as well
