I like it. "Blending" doesn't always mean smelting the render into the background, it's having both the render and background look realistic. Which, you have successfully done here. Naturally the edges of the render should get a minor light depending on its location. Hence, it's blended despite being smelted.
The signature could use a little bit of light though, it's quite flat at the moment.
I feel that the small caps in AWDLAW isn't co-operating with the large yet non-capital g, they're opposites which disturbs a bit. You should remove the Mmowned, to be honest, then move the Designer to mmowned's original position.
At first I actually thought the white lines where a poorly cut render. You should remove the lines next to the "wing" at the top, keeping the ones next to the bottom wing and those next to her head.
Other than that I like it very much, beautiful render too : o
