As of recent I've been attempting to make a wallpaper of the 'want you gone' interface of the portal 2 credits, but with intention to customize it with a few rain-meter skins.
What I wanted to do was remove the, logo, text and dots in the boxes seen below.

I assumed it'd be as easy as clone-stamping the background on the left side but I was gravely mistaken. When using this tool it expectantly dosen't incorporate shadows, i.e the orginal images background shadow. I'm not amazing at description so here's an image to easier identify my problem

As you can see notably on the top right is how the light levels are completely different due to the shadow on the background.
I was wondering if anyone could be so kind as to enlighten me on a method of fixing this.
Thank you
