Power Flamer Normally when I see an enemy like this in FallOut I run away, instead I think it's cool. :P
I'm pretty sure this was entirely a character animation test so I don't think I can criticize the lack of a background for this gif.
The one thing you could consider adding would be a 'small' amount of lower torso and leg movement, nothing major. Just enough to add to the breathing effect you were going for.
As well to add what VicariousE said below me is that it seems like the handle of the Flamer is being stretched on the right arm, a quick adjustment will make the weapon look like its a solid piece of metal.
A few tweaks and you're good to go. :P
