V1 is the best, but the text draws the focal off the render, and the green is a bit bright making it seem out of place.
your right about the text, i just felt anywhere else and it was just too distant... not part of the sig :/ maybe this is one that just doesnt need the txt ^^ and i'll throw together a version with the green faded
Your best imo. ^_^ Very nice lighting and effects mate. I'm really liking the feel of this one. ^_^ I suggest moving the text toward a corner. Not IN, toward. But for me, it looks good where it's at. Maybe move it a tad to the right. Good work bro.
