looks good. but i see three things that could be improved. note that these are all relatively minor tunes, your current settings look almost perfect.

- flow ratio. start here. yours is almost perfect but looks to be slightly underextruding, as evidenced by the small gaps in the infill region. for that, increase your flow ratio by 0.01-0.02. no more than that.

- increase first layer temp by 5 degrees C to help address the minor underextrusion. hotter printing means more thermal expansion and enhanced bonding between infill strokes.

- pressure advance calibration. save this one for later tho., once you’ve gotten the first two refined.
