The joke doesn't even work. The original worked because Hitler actually shot himself.
All you've really done here is equate Trump to Hitler, which is hardly original. Usually I wouldn't harp on about the premise of an illustration but the whole Trump=Hitler thing is way overplayed and this comes across as a not as good retelling of a legitimately provocative and edgy piece of art. Also I pulled up the Hitler original and it looks like you've traced the entire suit, hand and gun.
Good job on making the likeness instantly recognizable in such a high contrast stylization.
