Haha nope, not dissolve. I duplicate the render a couple of times then played around with some scripts and then placed them around and then erased what wasn't cool.
And the blurred thing is meant to be like that. I blurred the whole image, then made a cyclical shape around the render sharper to enhance the salience of Rachel Bilson. And due to the sharpness, that's why some of it wasn't as smooth. If you see like the bottom corners of the render, it's more smooth there cos of the blurriness.
