IdeazDen -- Compared to your other designs, I like the direction that you taken #28, #27, and #26. You have created a good minimalistic and pure feeling. However, these designs lack the "advanced" and "innovative" feeling that I'm looking for. Perhaps you can use some sort of gradient 3D effect to achieve this. Here are some examples:
