#32 and #33 have great pops of color- thanks for thinking outside of the blue/gray realm. The shadow effect adds a little bit of sophistication and looks cool without detracting or muddying up the design. One thing I've learned from reviewing lots of submissions, though, is that Sans-serif look cleaner and would better transmit on the different items we may apply the logo to [Website, brochures, shirts, mugs, etc].
