Looks pretty clean. Which lens you used?
Fujifilm 23mm/1.4 (@ f/8 ?...haven't checked the EXIF)on Fuji XE2s, auto 'A' exp @ ISO400 RAF file into DNG (in Iridient Transformer-X) then into Lightroom. In order to get less artifacts, I may re-process the raw RAF in Photo Ninja if I haven't lost it through deletion.
Added: Started to reprocess through Photo Ninja, but it turned into a time wasting project.
