Honestly Mitch, the image is crooked and lacks HDR effects. Good Effort nonetheless.
The subject is fascinating, and the tones in this b/w are great (I LOVE b/w HDR!) but yes, it's crooked and -2, 0, +2 exp. would have really helped with the HDR effect on this one. I like your efforts though!
My camera will only auto bracket max 1 stops. Is it time for a new camera then ????
