Learning how to use photoshop

This is my final edit for my holy trinity magazine, there are still subtitles and other pictures to go on to brighten it up, but this is my final edit for my main picture.

I made this using the lasso to cut out the image of Lauren i then deleted the background and used the edit tool to change the effect and look of the picture, i used the feather tool and changed the px to 10 when i cut out the picture this made the outside of the picture not look as sharp and blurred it into the white background.
