Your work is excellent, great eye, feel for details, composition and tonality.
Grain doesn't seem to be objectionable and tonality is beautiful. I should have ten rolls tomorrow and will start evaluating it in depth. My first tests were in Rodinal 1:50 but haven't printed any yet. I'm running between the digital darkroom today and the wet darkroom and will do a couple of test prints from the Foma in the next hour.
My first test was a week ago shooting a couple of brothers cutting tobacco. I shot KB 25 in the late morning and late afternoon and delta 100 in the mist of the early morning. I loaded a roll of foma 100 and one of 200 in my F2 and shot side by side with the delta 100. The negs look very good before printing.
