Eek, 8x10!! thats a bit grown up for me and I'm scared to say anything......I can't even lift one let alone work it. The nearest I get is a '72 rollei 3.5f! Seriously though, there's little to be said other than to congratulate you on capturing such detail and tonal range. B&W foliage can have the problem of looking too 'one toned' but this is great. The water at the bottom looks blurred suggesting a slow shutter speed, maybe an ND would have allowed a slightly less exposed (I hesitate to say overexposed as this isn't, this is purely a matter of taste and aesthetics) look to certain areas of highlights. Maybe dodging the bottom half a little during printing would help balance it out.
Really nice shot, I'm just not fit enough for a camera that big!!
