I like your style, Gogo.
1,2,8 and 10 really stick out to me.
8's use of C4Ds is just beautiful. The text kind of sticks out but I think it compliments it in a way.
The whole scenic look that 10's got going on makes the entire signature so much more interesting, the only thing that looks just a little out of place is the power lines in the bottom right corner. But then, maybe that's the effect that you were going for.
2, the concept is excellent and leaves the viewer wondering about a potential hidden meaning or story.
1, just one word comes to mind: truth.
Once again: I like your style.
