Blending objects into base image

[Neomite]

Does anyone have a great method to blend an object into a base image to look realistic. The edge softening and blur tools still make the object look out of place. I've tried all kinds of levels of transparency in combo with edge softening. The object and base image are not similar in colors either. Basically I'm removing green screen backgrounds from a subject and placing the isolated object into different backgrounds, but sometimes the edges stand out and don't look natural.

Depending on the image, I sometimes use the Bristol Smear tool. Of course if it's something like a face, you can't do that. In that case, I use the blur tool but I don't drag it... I just click. That does it for me!
