I agree with Jupiter!! With vertical sigs, I feel, the rule of thirds pretty much gets thrown out!! The placement of the render makes the sig seem very empty!! And I think what Jupiter was trying to say about the black white and grays is that they need to blend well together. I notice you do have black, you have white and you have gray.......but that exactly what you have, white around the render, then black, then gray at the top, they are segregated and not blended into eachother!! BUT, I dont want to put words in Jupiters mouth, thats just what I see!! lol
