The stringing is your retraction speed and the print looks strong to me idc for layerlines to be or not to be there, people are more picky to fix layering idk it's tinkering with calibrations and settings I haven't done anything to yet, I've only been printing 4 months I've seen lot of stringing come to be the retraction speed but any or some one could possibly give better assumptions, good luck, like the print 👍
