Nice image there- & I have sometimes felt that way too- not being able to capture the feeling/mood of what I'm seeing through the camera- Or seeing the final image later & thinking that's not what I had seen but then it can metamorphis into something even better. At times I feel I walk around with an imaginary viewfinder against my eye, zooming in & out on life, asking myself if that would make a good picture. But most of the time when I am taking pictures, I concentrate on leaving the periferal crap out without cutting off any parts of the initial subject matter... scalping heads, missing limbs, etc. I have to remind myself that I can always crop later. I have no rules, ...just thoughts. :)
