Love the way you captured the rifle going off, or is that some crafty retouching! Just a shame the subjects face on the right of the frame is in shadow.
Good detail, good strong colours, exposure is fine. I'd perhaps hope for a touch more spark compositionally - this seems just a touch straightforward, which makes it a not-quite image for me: there's a sense of not really knowing what your real point of concentration is here - the coats, the smoke, he decoration, the flasks and bags? Too many elements competing for attention perhaps.
