natural=tree_row should be used on a linear way not an area covering the foliage, see https://wiki.openstreetmap.org/wiki/Tag:natural=tree_row

Also please don't tag leaf_cycle and leaf_type as mixed as a way to tag unknown, only select it if they really are mixed. These all appear to be broad-leaved evergreens, but it's only a guess from imagery.

Further some of these aren't really tree_row, you've just drawn an area around a group of trees, it's better to just use a node for each individual tree in that case.

While additions of buildings and trees in OSM is very welcome and we appreciate any contributions, please don't use OSM as a playground for your own modelling work. You could take an extract for that and then use that data in private, otherwise if you want to contribute back to OSM I'm happy to help with feedback to improve your contributions.
