..this photo was from a years old 800 iso film? Does look pretty good to me; in general, and grain-wise!
Yeah you can "smooth" the grain with software, but it's difficult to retain sharpness, and make it look good and not like it's smothered in a way if you don't take a lot of time, treating different areas of the image individually and with care.
Embrace the grain! Grain is good (most of the time) !
On the subject of grain, I found a few time-capsule 35mm films in sock drawer that I sent to snaps with my recent batch - one was a horrid iso800 Lomo thing from about 10years back - everything on it was grainy as hell - can it be software'd out with e.g. with GIMP?
and that's probably the best of a (very) bad bunch.
