These are hurt by less-than-idea focusing and limited depth of field. The first two, shot #1 with the two pistols, and the second shot with the revolver and shotgun both have poor focus on you, and just slightly off technical values. The LAST shot is a near miss; if it were SHARP, it would be a pretty good image, but alas, it's soft. The contrast is also a bit too high I think; there are lots of dark tones, but your face, and especially your hand, suffer from being overly "hot" and pale white. Still, overall I think the leather jacket, hat, and that neat concrete wall all together is the basis for a good shot idea, but the execution needs a bit more work. Selfies are often very tough.
