There is no real dynamism here, it looks like all the characters have been lifted from somewhere else and pasted into the same image, there is no relationship between them. If they are gearing for combat, the very first they would do would be to actually look at each other. Eye contact and facial expression would be the key to building the tension and telling the story of building to a conflict.
At the moment the orc is gazing off into middle distance, the foreground elf is aiming at the floor for some reason, and the golem seems quite intent on striding towards something it has seen either behind the orc, or beyond the frame. The figures in the background are far more effective in this regard.
Perspective is a bit odd as well, the elf is tiny in comparison the the orc, and even though she is sitting in a tree she appears to be lower than the orc in the composition.
