Well done. It's a great, if strange feeling not have the instructor siting next you. I also talked to myself whilst flying around the circuit, and still do. I think it is a very healthy thing to do - you have to be your own instructor when you are flying solo, so keep giving yourself feedback and don't accept sloppy flying ever -always fly as you have been taught.
A great comment about the Meerkats! And nice to see that the instructor didn't just slope off for a coffee while you were up there on your own!
