>>2125783Hello, dear Anon. I am not harsh at criticism as other people here, but your render clearly had white spaces left and white left-overs. I would suggest putting flat colour layer under render's layer, when removing backround, this green works best.

And this green isolates most of renders' edges - tried it on many pictures. Also, don't be scared to turn up brightness of your device, when you are making renders, white left-overs can be tricky thing to remove. I cleaned render up, but I hope you are going to take my advice into consideration next time. <3
