I don't like the one C4D just sticking out to me it looks odd. The Text looks fine where it is. Trust me, not all sigs need the Text close to the focal.
V2 has great affects but I like the simplicity of V1 better. But I do not like whats on his shoulder, Fuel Rod? or just an effect? Either way I find it takes away from the picture. and BTW, I like the left side of V2 better.
I think its an effect, not a fuel rod. I like the text where its at but I dont really like the blending in the v2. Overall pretty damn good sig. 9/10.
