I really like the Neomorph on the ceiling behind Shaw. They're more or less evenly match. The Neo has the element of surprise but if it makes so much as a single sound, Shaw could turn around and it would end up wearing an axe in its face. That will knock it off its perch. A few more blows will finish it.
Great sense of ambiguity as to who is going to win this encounter and keeping the viewer's gaze upon it, attempting to work out who the victor is going to be. Despite the Neo having an advantage, it's not as strong as a Xeno and we know Shaw is no helpless Princess in distress.
The other images are more or less foregone conclusions. Nice compositions, poses, diorama sets and lighting, too. In all of them.
Regardless, you're getting really good at these. Huh.
