I like where this is heading but it is a little bit too similar to the McCombs Business School logo...we like their concept but don't want to rip them off directly. As I was saying in the general discussion post, I think it works out great the way the burnt orange forms a "T" shape. So T and M are in the letterform...if we could get the i in there that'd be even better -- and set us apart from that McCombs logo.
Also, I like your use of the dark gray/silver. Very complementary.
Of all your submissions I like #24 the best but would like the grey color in #1 to be used to better distinguish the "i" from the rest of the letterform.
Also, we are interested in seeing some logos that include abstract graphics to convey scientific innovation/research excellence. Thank you for your continued submissions!
