@Orladini, I'm afraid none of these images you have posted are of good enough quality.

The edges in all of them are a bit jagged, there is too much space between the top of the head and the top of the canvas, as well as between the bottom of the chin and the bottom of the canvas. Have a look at the guidelines and tutorials in this thread for information on what we're looking for in our cuts and how they can be achieved. If you have any questions or problems, just post in there and we'll guide you accordingly.

If you post the sources for these guys in the meantime, I'm sure the community will take them on 👍
