The heavy line at the "high water line" is contour 105'. I think you are showing where that contour line crosses the section cut BB line as slightly higher. (I know the west contours are slightly up for interpretation in this alt, however, so not likely to be an issue on the real exam.)
I would suggest where the contours cross the section cut line twice, rather than drawing it as flat between the two points, interpolate a little to have a slightly smoother (and more correct) grade line. Not sure how important this is, but it's what I'm going with when I test tomorrow.
I suggest drawing a few more sketch circles for the high water line setback than you have shown. Affects the surface improvements area slightly.
Other than that I think it looks great!
