Looks good for second time out. Lower body looks ok, but upper body is where i think you should focus.
In the 5th pic it looks like you are too stiff on the clip-ons, and using them to suport your upper body. Try using your side leg and the inside of your outside leg (gripping the tank) to support your weight, and relax your arms.
Also try moving your upper body down and get your head closer to your hands - your head looks like it is somewhere near the centerline of the bike. In the right hander, it appears you could be looking further thru the turn, but hard to tell b/c I don't know where the track goes.
Play with various styles, b/c everyone has a different way of doing things, but those may be helpful in getting more comfortable.
+1 on thatTry riding with the pegs in between the balls of your feet & toes also. I noticed in all of your pics you have the pegs in the center of your foot. This really helped me get better balanced & more aggressive.
