Hello,
You added a number of culverts (tunnel=culvert) in the forest in Orlické hory, declaring CUZK ortophoto as the only source. However, I can't see them on the CUZK ortophoto, except for those that cross the main road. (Even some of those are not positioned correctly.)
According to my experience, it is next to impossible to correctly resolve intersections of small waterways and forest paths / tracks without on-site survey. I would bet that in 1/2, maybe 3/4 of cases you would not find the  culvert you mapped OTG in reality. There may be fords or bridges there and very often there is no trace of any waterway at all - the waterway may be intermittent or incorrectly imported into the map data.
I believe this is a harmful practice. It happened to me as a map user that I arrived to a 40cm deep ford where an unnamed OSM mapper added an imaginary culvert. You do not want to be responsible for that. Adding speculative culverts or bridges also makes it difficult to those who want to resolve the intersection correctly - as the situation seem to be already resolved. Additionally, the ways or waterways are unreasonably split, causing part of the way history to be lost and complicating further edits and work on relations.
