Your pictures are excellent.
In the mid 1980's, I went to Colorado and rented a motorhome for a vacation. Toured both the northern part of the state and the southern mountains. Took lots of pictures with my 35mm camera using slide film.
When I got home, I picked out several shots to enlarge and frame. They turned out to be much poorer quality than I had hoped for. (in hind-sight 20 years later, it was a combination of poor technique and the limits of a small negative).
This started me out on a quest for razor sharp pictures and the equipment that could do it.
I use a Pentax 6X7 which does almost as well as a 4X5. I also have a Mamiya 220 twin lens reflex that also makes excellent photos.
Large format I have a Tachahara 4X5, but because of the weight, bulk, expense, and time required to use it, I have used it very little over the years. (maybe after I retire I wil have time
It is true that 35 mm films have improved greatly in the last 20 years, but so have 120 medium format films.
But for most snapshots of the kids, etc, I use a Nikon Coolpix 8700 digital camera (8 meg). You can get razor sharp pictures printed at 8x10. I have never tried anything bigger with the digital.
