This and
This.
I saw win.
The first one, is a very cool idea. Did you use a stock? I like it a lot. The way you multiplied it all over, and distorted it reminds me of glass or something. It's very bright (but not too much), and has a clean and cold feeling that I find very suitible.
I don't find the text placement to be in the best place, though. Or maybe it is and you just needed a different font. I probably would've also added some clipping masks, starting at your focus point and spreading outwards. But that's because I'm insane. Keep fidding around, it's doing you good.
And now, for the second piece, I'm drawn in by the colors. And then I'm fixated by the effects. I can see some lovely C4D work and...smudging? Is that it? I'm awful when it comes to C4Ds, can't do it.
I'm very jealous of that friend of yours, I want this signature. XD Will you make a tutorial for this one? Looking at this piece might take me to the point of obsession if you don't.
