Custom B-day Cake Photo Swap

[MindSplit]

My cousin's fiance is having a birthday this upcoming 1st of October. Now we have both decided to make him a custom birthday cake with a Michael Jackson theme. To take it a step further we want to face swap her fiance onto MJ's body.


This is my attempt at it but i feel it could look better



If some one can assist me on how to make this look better or lend me a hand in making it i would greatly appreciate it.


I have attached the 2 files I'm working with.
