Not bad, I think what jumps out at me is that your all the way back in the seat with arms outstretched in some of the photo's. That position in my opinion isn't quite right, but that may just be because I "crotch" the tank instead of sitting back. I would think with your arms out further you wouldn't have as good of control, but I would really need to actually see you riding to confirm that. I know that some instructors preach about using the thigh that is "on top" of the gas tank to help throw the bike into the turn, the further back you sit in the seat the less effective I believe that would be.
Do you have any complaints in how your bike handled in any way? For example did it turn like you wanted, or did you run wide in turns sometimes? Do you feel like you can go faster than what you were, or was there a variable that was prohibiting you from doing that (like loss of traction, unable to hold your lines in the turns, or just lack of knowledge/experience how to do so)? In the future (if your looking to improve) I would highly suggest writing down your thoughts about each track session IMMEDIATELY after getting off the bike, the 1st several minutes after coming off the track will have the most unpolluted memories of what just happened, the more time that passes the more you will lose accurate memories. Keeping a simple log book is an invaluable tool in getting better by having a record of what you have experienced, what you did to try and improve, and what happened as a result of those changes. I don't want to make things seem complicated, but something as simple as a basic log book will help even those that have absolutely no desire to race and will give you something to refer to when asking for advice.
