your scans look horrible, and not like what I've seen from pan 50 or any slow film. you ought to try throwing these negs in an enlarger.

I will try it. This negatives was scanned with Noritsu S-4. Pictures are crops form original scans. I will send negatives for scaning with Nikon Coolscan 9000ED.

In my opinion, structure of water on first picture is horrible when I compared with structure of water on second picture.

Do you remember how what is the exposure for that last shot or most of your long shots?

Yes, exactly. Last shot (second picture) - 156 seconds. In a general way, my esposure times are 56s or 156s or 437s with Hitech 10 stop filter (156s or 56s is standard with f8 or f11 at EI25).

exposure time = metered time ^ 1,485 (equation derived from ilford pan f+ reciprocity failure datasheet)

The negative looks very good. Section of sky looks smooth or normal from BW film (no structure as on my rolls of Ilford Pan F+)
