i dont like the second one, there aint much to draw your attention to but the overall presentation isnt too bad , atleast its not overdone which is better than some people who think more is better (its not, just a tip)
the first one is pretty nice, but its like theres special stuff over the render, then theres special stuff in the middle aswell. just a little too heavy on the deatils, but other then that its pretty nice, and an individual sig aswell! dont see many like that nowadays xD
