1) if you don’t do the wye valley suggestion before chepstow, change your route into chepstow slightly. Your route comes up a longer main drag of a hill, the purple I’ve added is a much smaller road through a hidden little farming valley that is lovely.
2) you’re skirting the bottom edge of the Cotswolds and sticking near the m4 motorway - it’s great countryside but a little further north (Sherston/Tetbury/Malmesbury) is more cotswoldy and prettier. If you want to stick with your current route (which will be awesome) add a tiny detour (it will add a small down and back up) into Castle Combe which is a beautiful little Cotswold village very near your route.
3) if you find yourself needing somewhere to stay near Wootton Bassett send me a pm!
Castle Combe is a good shout, it is a bit of a landmark. The couple of pubs there are bike friendly and serve coffees.
Sherston is also nice riding, the Angel cafe is good but I would turn right at sherston and go through Foxly to malmesbury, it is a much quieter lane.
