On #8, I like the gradient, but not the ".com" on the top. The font is not very special, so I will work on it more. Eliminate the shading on the bottom, we can add that later. Thanks!
#12 - #16: Heru, this needs creative and conceptual elaboration. It feels like you are providing six different fonts with gradients and other effects. We are looking for a memorable logo that communicates what the brief states. Thanks.
