@rmbrasil, we've given you plenty of guidance on multiple instances for how to save your cuts to avoid have such a large file size, so please keep it in mind for future cuts that you do.

I'm rejecting your second cut as the edges aren't smooth at all but rather quite jagged.

If you use remove.bg and photopea.com/Photoshop, and the respective tutorials, you should be easily able to provide better-quality cuts in a quick and easy manner.
