Hi & (a little bit late!) welcome to OSM! Thanks for your work but one little thing to mention. waterway=dock is used for actual drydocks - in OSM, jetties like this one are tagged as a https://wiki.openstreetmap.org/wiki/Tag:man%20made=pier?uselang=en, either as a node, as you've done here, or as an area, following their actual outline. Thanks!
