Not really sure what you were going for in the first one, it seems like too many idea's though. nice coloring though.
i like the bg of the second one, but the render effects don't do it for me. the text is iffy as well.
I like some elements of this, but most of it doesn't work. the text doesn't work, it's sticks out too much, and the font doesn't fit. i like the render work and general coloring of the sig, but feel that it would benefit the sig if you took out the second render and the diagonal lines stock. it...
