I might be seeing this from the wrong point of view but there is no blending at all :s
Not that is bad though. the bg is actually nice.
After practicing my smudging, following countless countless online tutorials, and a shit ton of patience, I present you a smudge tag.

Gotta say it would like nicer with some coloration and blending, but good job nonetheless.
Smudging doesn't look too bad at all. But yeah, def need to blend that render in, and that blue color of the render contrasts big time with the flatter hue of blues in the bg. Good start though, I would consider this a wip bro.
