Marksman Loads Another Round in the Chamber

Still learning to use Photoshop, any criticism is welcome. I would put a comparison but the site seems to be down at the moment. I will just put a link to the original http://i.imgur.com/pNIJ9.jpg

The smoke is weird

Need to feather the edges on your glowy bits a bit more. They’re still pretty obvious ovals.

You can tell that a brush was used for the smoke because I see rectangular edges around it. If you blur/smooth those out a bit it will be a lot better. Also, I think just a smaller wisp of smoke would have a better effect than the whole cloud you have going on.
