About entry #14, i dont like that kind of Matatena, im liking more other styles.. like entry #11.. Maybe its the shadow and the inclination.
About Entry #15, the inclination of the Matatena is better, but the shadow is too big.
The typography is not my kind also.. maybe something like in entry #12, or your #17 and #18
Entry
#16...We need something "bolder"
#17, and #18..
Yes! i need a logo that i can use with white and black background.
The symbol its a new idea that is really good. lets try that also.
About the typography, we could play with that also.. its not what i expected, but i like it
