Hi Jason... my turn for lots of catching up now!
Communication - nice take with good, effective PP. I do agree with Graham (
@overbez ) that as it's B&W more contrast would work well on the key. I like that the shadows are pretty much consistent, too.
Dark - I really like. The shadows could be lifted but I think it'd be a slightly different picture then and I like it as it is. Really good conversion and technically bang on shot, which for me might benefit very slightly from upping the exposure at the top end of the curve so that we have less midtone and more highlights, especially on the foreheads? But that's being super picky and might just reflect the fact I like super high contrast in B&W!
Big - nice job, lovely shadow and great background and POV. So much to tick in that photo. The only thing which puts me off slightly are a few blown highlights on his shiny helmet - it's a very difficult subject to light in that regard and pretty certain I couldn't have done better. Might have been necessary to do some exposure blending, perhaps? Still, it's bloomin' fantastic.
Cut - I like it... but I think I prefer the previous two! It's difficult to know where the PP starts and finishes which is both a positive and a negative! Very cleverly done and still a very high quality image but that's the problem when you keep resetting the bar higher and higher
