Im impressed... The tag is amazing, the use of topaz is good. The composition is perfect. V2 (B/W) is better as the colours in the first one aren't too great. Overall, really nice tag
b&w version looks better, though I feel that the render position/effects could be in a different area.
I think that your focal point, the render is too distracted from, because of the tree. Not to say it's not an amazing sig at all. Very cool.
