Hi Knash2, welcome to the forum!
Your scans show a good quality burn.
The PIE values in the Sum8 scan should be no higher than 280, and the highest value is 71 so that's good (but not great).
The PIF values in the Sum1 scan should be no higher than 4, and the highest value is 2 so that's very good - it's virtally impossible to get a maximum PIF value lower than 2.
Have a look around in the forum at other peoples results, especially those scanned with a Plextor or LiteOn burner which is easier to compare with your own scans(*). In time your understanding of what constitute good and bad results will get better!
(*) Because PIF are reported per 1 ECC block with both Plextor and LiteOn drives, whereas e.g. BenQ drives report PIF per 8 ECC blocks, and NEC drives report PIF per 1 ECC block or per 8 ECC blocks depending on how the user has configured CDSpeed.
