First off, very great story telling.You know somethings happening in the picture.
Colors.This one has a very good "color mood" which happens to be appropriate with what is happening on the scene.The balance of dull and high contrast colors is great.
Perspective. The tilted view creates a great impact.
Composition and Texture. great texture and detail on the nuke bearer*(is that what they are called now?).The balance of overall detail in this piece is well made.The details on the main subjects/focus on this piece; the nuke(in terms of color) and the NB*(in details) are top notch.
