I too have been dabbling with TMX after not using it since the first try years ago.(posted 8568 days ago)I found that when developed in a "standard" developer such as D-76 1:1 it just doesn't look very sharp, or iow shows low acutance. Careful examination of the neg shows incredibly fine detail, but prints just don't have any zip.
My solution has been to go to Rodinal 1:100 or TFX-2; those developers give much higher acutance, probably at the expensive of the finest detail. But the prints look sharp!
Overall, with what little I've shot, I like TMX these days for some subjects while I still prefer Delta 100 for others, usually people.
The only problem I've had with TMX is that it's rather sensitive to standing waves in drum processing (sheetfilm), giving a fairly broad line of excess density that isn't seen with Delta 100 or HP5.
Nice shot, btw.
