My first reaction is to say "Great, anyone can do that with a medium format camera. I guess Khuram just bought a Leica S." (just saw a bunch of photos taken with the Leica S and I have to say, I was completely floored by the technical quality).
But nope, it's just a shitty Rebel
Which brings me to my point: Technically, the image is very very impressive! Focus is absolutely right on. Second, DoF is perfect too; not to shallow but shallow enough to bring into focus multiple aspects of the image: Fingers, watch and eye-piece. But it's shallow enough to throw the pink shirt and background out of focus so that color becomes almost detached floating. Clever, very clever!
The dirt on the fingers also provide credibility to the man's profession. This isn't just a posed photo op.
To summarize, Khuram, one of your best, in my opinion!
