This isn't a very good cut @Razvan Stancila. The edges are very jagged and not smooth at all.

Have a look at this thread for more guidelines on what we expect on our cuts. I will be rejecting your other cuts since hardly any of them have the dimensions we required, have too much space above the head or below the chin, should be rotated etc.

You should also watch these videos to show how easy it is to make cuts, one using Photoshop to do so and one using photopea.com
