OK, now I can see your photo. I don't know if you changed something or if the previous problem was part of the problems the site was having.
You still haven't said where you are. The pruning job doesn't look great, but is OK. Question is the timing. If you are just going into a hot summer period, that is a bad time to stress a plant like that. Where I am azaleas and rhodies are still in bloom. In bloom would be a bad time to do it too. Rhodies are usually pruned right after they finish blooming.
In any case, an established rhododendron is pretty hardy. It may be set back a bit, but should survive. Don't fertilize it, just let it rest and recoup. Keep it well watered and provide some shade, if it isn't in a shady area.
