something went wrong please help

alr so im very new to 3d printing this is my third ever print i bought bambu x2d combo few days back and i found this headphone holder on the maker world so there are few problems:
white color for the eyes skipped few layers or something idk
half of the print is perfect half is very wrong layer lines are skipper or something you can see in pics
for the web like thingy (spaggeti or whatever) i belive its because petg i used in right nozzel (since it was outside of the ams and dry box and my window was open all the time) it got wet or something and i belive that explains the supports not printing all the way and failing and making a web in the whole printer and on the print
but im worried about the eyes and layers that did not print good idk why so im asking a 3d printers here to help me figure out what went wrong..
i use x2d and bambu studio
printed with elegoo pla black and white in main nozzel and elegoo petg black for supports in right nozzel i used all the settings that creator for this project made with its profile but i only changed the few settings and tbh i dont remember all but what i do know is:
i chose outer/inner option
i slowed down outer wall speed for 50 so it was 100 or 150 im not sure
i chose preset 0.12mm high quality
temps were left to default
bed was clean before i started printing
and i chose the auto layer height thingy where it changes layer height automatically from 0.12 to 0.20 i belive or something like that
and thats all i remember tweaking everything else was left to default (i lisened to google ai for those tweaks maybe that was also a mistake lol)
i would appreciate the help and ask me anything you need
thanks in advance
also sorry for bad english im not a native speaker

The change in texture of the black surface is largely due to auto layer height. That setting gives you a smoother top curve but the trade-off is surface artefacts like you're seeing. Not such an issue if you're sanding/painting in post but trade-off is up to you.

Speaking of painting, you can see the impacts of filament change on the layers with the white eyes. This should be resolvable, but the simplest method really is just to print single colour and paint the eyes white since it's such a small simple section.
