Looks good.

As for the issues it could be a few things, nothing major.
Stepover, I use 45% for roughing, looks like you might have went higher? You really only want to engage half of the cutter into the material. This is where climb vs conventional cutting comes in.

Perpendicular tool. I made a little perpendicularity tool on thingiverse to check if your tool is reasonably “normal to” your work surface. If it isn’t I usually just put a layer of tape or two at the mount to adjust. This can cause your tool to cut at an angle and is usually more pronounced in one direction more than the other.

If I am wrong on both of those it is just a feed and speed thing.

Your cuts are obviously very good as is and a few very minor tweaks will take it to the next level.
