Maybe the general public doesn't notice tip offs to concealed carry so your setup may be ok. Since you have your HCP it really doesn't matter. But the flap on your belt and the belt sag on that side scream "I am armed with a gun in my pants".
I make a game of it out in public by trying to notice who is armed to increase my awareness. The biggest problem with IWB holster is the belt attachment that is a give away. Some are small and work with a .380 which I usually carry. Business attire is required at work so a smaller pistol is in order. I have almost went fulltime to OWB with a light jacket or fashion vest most of the time. Again, not one of those photographer's vest, they also are a tip off to going armed.
