This is an interesting idea, although the billowy smoke coming out makes it look not like a real shotgun blast, almost like someone blue smoke from a cigarette down the barrel of the gun, Also from the background I'm guessing this was taken indoors. The narrow crop doesn't work for me in this situation either, the crop and the border together make this shot feel cramped. Again, I like the idea behin this and have tried similar shots outside myself while my husband is shooting, tough to capture!
Great smoke capture. Always find it so difficult to take really good pictures of smoke. The blue really helps to contrast it. My only complaint is that I wish it wasn't cropped overall so tight.
Interesting concept, and very pretty. I'm very curious to see if you get any complaints about the size, since you didn't max out the image dimensions in either direction, and have a border to boot, but it didn't bother me.
