>>1731585Are you using photoshop or gimp? In either one, you can create different layers, which are essentially separate stacks of images. Take a look at a quick tutorial on layers and layer masks, which allow you to hide or reveal parts of a layer. You can put a temporary black or gray layer behind your render so you that can check for bits of the background you missed. Also, your render was really not all that bad, but you should take note of what that other anon mentioned. I've seen plenty worse here, but that doesn't justify mistakes you made. Here it is with some quick touch ups. Not perfect, but I think good enough. I find that adding a black cutout behind it with a 1 pixel gaussian blur helps hide bits left from the background and makes the edge smoother. Keep in mind I'm no expert either.
