@TiagoSeattle, I'm not sure what technique you used but the final cut was much more blurry and lacking sharpness than the original good source should produce.

I again remind you to crop the original source if you're going to use remove.bg, otherwise the final cut won't be as good as the source.

The remove.bg website decreased its original resolution.
I would have to pay to download at maximum resolution.

As I have explained to you a few times already, you need to CROP THE ORIGINAL SOURCE, to an area around the face. I explained the process to you here already. If we take the time to give you feedback, please take the time to read it and follow it 👍

Watch the below video to see what I mean: 

Sorry but I am not fluent in English so I may have missed some information that you have passed on.
It is not out of laziness or neglect.

As I said before I just want to help and I'm sorry if I take more time to learn. 

I may be in the way now but after I learn you can be sure that I will help a lot 👍🏻

If you don't think you've understood something, just ask. Don't just do whatever you think is right, it might not be necessarily the case.

Watch the video and follow the process and the keystrokes, even if you don't understand what is being said. It's quite logical anyway.

Remember, crop the source before using remove.bg. That's commandment no. 1.
