Double meaning image

After the consultation, I was asked to change the drawing I did for the first image. I was suggested to used the movie "Dexter"'s poster as reference. So I did and I also added a female partner also as recommended. So I came up with this:

Here, I have drawn two couples together to get a clear view on how I want the outcome to look like. At first, I drew the man as similar as I have drawn in my previous post. Then I thought of changing the man into a weaker looking and less muscular kind of guy.  The man has a knife to show that he can also kill and his shirt and face may be covered in blood stains too. As for the female, she also have the same approach, that is an innocent face with blood stains. Also, she is grabbing onto a child showing that she can also kidnap them. For my photo reference:

The bloodstain face
