Airgirl, I think you need to adjust your expectations a bit. No flight is ever perfect! On every single flight throughout your flying career you will make mistakes. That's normal. As your flying skill increase the type & severity of mistakes will diminish but there will always be 'something' that could have been done better.
If you're not noticing errors then you're not being observant or have become blase. Being able to recognise what & why something is wrong and then working out how to correct the issue is an important skill to develop because that's how you learn & improve.
As well as being able to recognise & correct errors, it's also important to be able to distinguish between critical, flight safety items, and relatively inconsequential ones and then act on the most important ones from moment to moment. You'll be ready for solo when the critical errors either don't happen anymore or you have the ability to recognise & correct for them while ignoring or delaying dealing with the inconsequential.
A long winded way of saying 'Don't sweat the small stuff'.
