Much better on the border.Another good way to do borders that I have found is use 3 pixel with blue(or whatever color that mathes your render) set it to overlay then make another with 1 pixel and use white and set it to screen or overlay.Good sig though,background and render blend well together.
The colors are balanced and the sig itself is balanced. I don't think you did as good a job blending as you normally do, however and the picture to the right looks flattened slightly. Good sig IMO but is lacking compared to your best.
