Those are pretty nice, and you have a lot of effects going there. But, I always like to see logos that can stand on their own in black-and-white as well as looking good with text effects, etc.
The crinkled paper/foil effect helps to provide a technological feel to the organic shape of the mos image. I hope that didn't sound too artsy, but that's what I like about it
Hmmm I know that looks good but I really didnt get what you mean by it hehehehe I'm no artist i just design things, whatever I think of I put in, if i dont like it I undo it and redo something else that I think is better.
