Cutting of the body is simple. You don’t need to wander about this topic. Just use Pen tool
There are several points you should not forget.
- After creating the path, Save it.
- From the path, you can create the selection by one click. Click the botton ‘Load path as a selection’
- After making the selection, Add feather.
I like 3 – 1 feather. Why add this? Because if you don’t add the feather, the edge becomes too sharp and it will not fit with the background.
