Wellll...he's looking off to his left, kind of at us, his arm is pointing away to the right, and the beam is angling downwards somehow. You'll better serve your picture idea if everything's lining up. Leads the eye, makes for more drama.
His body is completely obscured by armor, but I don't find the underlying anatomy plausible. I don't see how there can be a proper torso in there, or a proper right arm. Even with extreme armor, you need to start by sketching the body underneath.
On the other hand, the fire is rendered pretty well. I don't think the metal looks awful; it looks okay to me. I like the little smoky figures in the background. And if you lined everything up, I'd like the composition. And the yellowy/purply color thing you've got going.
