You asked for it.

(First-Timer Notice: I do sound harsh, but it's for the better. I wish to tell you up close and personal exactly what I see that could make the shot better, and what is dragging it down.)
Airplane has plenty of "oomph" but that sense of "oomph" is being robbed by the boring angle for me. The angle you have on the plane is really nothing special, it does nothing for this screenie.
This being a "speed" shot, you have that sense of speed communicated quite nicely, but once again, the angle isn't doing much to help that sense.
There is nothing in the background except a huge wall of gray. This makes this shot look rather boring. Having recognizable landmarks or clouds can work wonders for the depth of a shot, this one, it is quite 2d. Speed really needs that third dimension so you can compare the moving object with the non-moving, in mine eyes.
Apart from the lack of an exciting angle to help back up the sense of speed and absence of a 3rd dimension, this shot is OK. Try to keep the solid gray clouds to a minimum in your screenshots, that can help them a lot. It makes for a much more eye-catching background.
Best of luck in you future endeavours. I hope my advice was helpful.
