This is a well-prepared talk, so I don't have too many suggestions for you.  Overall you finished with plenty of time left, so you can consider going into a bit more detail on some of your figures.  In general, it's good to describe the figures as you present them, which will take a bit of time.  But you finished with at least 2 minutes, so I think you could do that.

Slide 3: it would be good to define sTGC here, as you already have the words written out.

Slide 4: it wasn't clear to me what the x-axis is in the figure.

Slide 9: I had a bit of a hard time following the figure in the lower left.  This would be a good place to slow down and explain in a bit more detail.

Best regards,

Wade
