Besides the fact that Adobe moderators do not accept easily such digitally modified pictures, you need to be aware that the work you present here is not well done. Just to give you a hint:
The hand should melt perfectly into the background. Instead, you have aliasing effects and this border effect that you see always, when the original background is lighter and the artist did a sloppy job and did not compensate for this.
Also, the hand shows that the original picture of the man did not have the required quality for stock. Taking a bad picture and modifying it digitally, hoping that it will be accepted does not work.

Thanks for answer. You are right about the hand. What you think about the other images?
I agree with @jacquelingphoto2017.
@Pavel Slavov to do what you intend to do you really need to start with quality photos, and then you need to do perfect editing. There are several things that are quite difficult to do. The most difficult in my eyes is to cut out hair correctly.
FYI: The Bulb-picture has been accepted by error then, as the Mickey Mouse T-shirt should trigger an IP violation.
