I edited this for forbehs editing contest, and I love it so much I made it the cover!
Choose a color background of your choice and add your two pictures. Place them where you want them and DO NOT press the check mark. You want to erase the hard line first on both pictures; then press the check mark.
Then press Effects and select Artistic. Then scroll through the options till you find Shear.
Then adjust the settings how you want it. The red circles tells you what I did to my edit. DON'T press the check mark yet. You have to erase the shear where you don't want it. All you have to do is just run your finger on the picture. Erase till you're satisfied.
And you're done!
