Hello. I'm a beginner at using paint.net, and I have recently been using it more to edit screenshots for memes. I need some tips on how I can move and remove objects cleanly. Here's an example.
This is the one I chose to edit, and
this is the end result.
My goal was to move the arm to make it look like the girl was dabbing. I copied the arm to a new layer, edited and moved it, and erased the original arm using the brush and dropper tool. As you can see, it's not as clean as I would've liked it to be. How can I make the original position of the arm look cleaner?
