@Elihu Castillo, these aren't bad by any means but please remember to use remove.bg to get the background removed, if you aren't already. The edges aren't as smooth as I think they could be and I'm afraid a fair few of these aren't good enough to be considered improvements, especially when the current megapack cut is of a good quality.

Also, leave no more than 2-3 pixels beneath the chin when cropping. It's a facepack, after all, not a face-and-neck pack 😉 Same for above the head. And try to have your cut in the middle of the canvas, it looks a bit strange in-game if it's clearly closer to one end than the other 👍

Ok I use the web maybe the original photos were like that but thanks always for the feedback. 

I see what you mean but if that's the case, then they would need a bit more work in the future before being uploaded as game ready 😉

Or upload the original sources and let the community take care of them 😉
