in that photo, the square you have used to confine the color inversion actually disguises the gun. there is far too much going on in that photo. try eliminating a few elements, such as the plant, book, etc. and closing in on the gun.
is there any way we can report people who leave unwarranted negative feedback? I am perfectly willing to take negative feedback when it is deserved, but I have had a problem with someone leaving a negative with only the word "hater" and doing the same to another reputable member, and then leaving positives for multiple members with only the words, "not a hater".
