Can I tell whose POV I'm in in the first paragraph? If not the first paragraph, is it clear in the first line of the second paragraph?
What is the main emotion felt by the POV character? Do I show its opposite in the scene?
Where is this set? Have I described where we are or could this be anywhere? How can the setting help with the mood and emotion of the scene.
Is there a build-up? What does it promise?
Is there a pay-off? enough of a pay-off? Can there be more?
How can I push up the tension?
Who is in this scene? Is there someone in the scene who isn't present physically?
What is the relationship between these two characters? Is there a resentment between them? Does it show? How can it be more tense?
What is the character doing? Does it fit?
What is the character NOT saying? How can I show it? How can I show it better?
How does the character change in this scene?
What happens in this scene? What's the point?
Does it advance the story? How can it be made to if it doesn't?
Does it show us something about the characters? How can that be added?
How does it begin? Can it be improved?
How does it end? Does it convey a surprise? Does it make the reader want to read onto the next scene?
What do you do / think about when you revise?
