1st is good though I don't like that C4D sticking out from nowhere ._.
2nd is better I actually really like it ^^ Still that C4D in front is like out of place
3rd. I like the lights :D though it lacks Flow
4th. Wow this one is nice. Still i would dodge the lightning's annd make corners and other stuff darker so it looks sexier.
5th. cant understand a thing ._.
6th. Hmm nice smudging but that Lightened C4D effs the flow up a bit.
7th. I like this one too. Still it is like that upper corner gives the light and rest of piece doesn't get affected by it ._. You should have made darker the down left corner and stuff
8th. It better be something good
