Another thing that may help along with the advice above is overlaying a grid onto your reference (example below), that way you'll have a better idea of where the feature need to be placed. You can also copy and paste the grid onto to your sketch with low opacity so you can get a clearer comparison between the two. After looking through your sketchbook, it looks like you work really hard, so I'm sure you'll get it in time.
