Hi PGio,
another welcome from my side. Great work, just go on!
A side note: I saw that you mapped a couple of road gullies or manholes. Please be aware that at the time being the tagging of these objects is under discussion (here) and I will be working on the wiki pages soon.
Only those manholes which are made for a person to enter into a shaft to inspect drainage channels should be tagged as man_made=manhole + manhole=drain. Road gullies also called stormwater drains should be tagged man_made=storm_drain + inlet=grate. If you want to map more of those, please have a look at Road inlets and covers - OpenStreetMap Wiki.
