Hello Karl Maps,
Welcome to OpenStreetMap :)

I'd like to add a few things to my predecessor's words since you asked for review of your changes.
As bxl-forever mentioned, it's really hard to review a changeset covering half a continent because the usual tools won't load it properly. But that has already been mentioned.

Then: You said you cleanded Rennes but you never mentioned on what basis. We can only guess. So in the future please give a good source for your actions. Either within the comment or using the "source" section before uploading.

You deleted a few things. Why?

Even though you're pretty new I'd like to mention the concept of lifecycle prefixes since they cover quite a range of cases that make deletion of an object unneccesary: https://wiki.openstreetmap.org/wiki/Lifecycle_prefix

Maybe you can elaborate on the reasons for your changes. Until then I leave you with some helpful articles of the OSM wiki.

Happy Mapping
