i preffer to use 0.16 layer height as it does a great job at hiding the lines
it does slightly increase printing time ,but it is not much compared to the extra quality you get with it
if you want to even go smoother i would use 0.12 layer height , but this increase your print time with 50% if not more, but “should” hide all lines
All FDM printing will have visible layer lines. Carbon filled or a Galaxy filament have additives that camouflage them, but with any filament you will need to post process to completely avoid seeing lines.
I would also recommend checking the yellow filament, to ensure it has a consistent diameter, as it can influence the external look of the print.
You might also need to slightly lower the flow rate for that particular filament to get even better results.
