Is this considered good cut?

No.
Several things will cause that:
-not enough air pressure
-worn nozzle
-to slow cut speed
-
I would also say to much current, but not exactly the same result, so i will just throw a stab in the dark at very, very low accelerations set in the config.
Edit:
I did not read the settings when i replied, i just browsed over them, so yes it is low acceleration, but probably there is not much more you can do, that is very small for plasma cutting and would in the end require very small nozzles or "fine cut" as Hypertherm calls them.
Now i would say it might be improved a bit, but not "earth shattering" changes.
Try something thicker, at least 2mm or 3mm then some 5 or 6mm.
There is a procedure i do with my machines to tune the cutting and i can not recall if i posted those here, so here it goes in short:
-tune the cut speed and THC roughly with 3mm material
-tune the air pressure till you get the best cut, does not have to be perfect
-tune the THC by raising or lowering the voltage
-tune the feed rate/cut speed
rinse and repeat for other material thicknesses and nozzles.
This is something you have to do for anything that changes, sometimes even moisture in the air will affect the cut quality, and we do get a lot of moisture despite no sea in site. All mild steels are not the same, etc.
Also, after all that you can test with lower or higher cut current and how it effects the cut speed.

Did you notice i edited the post?
I saw you clicked on thank you after i posted so probably not.
