Nice, I am surprised how well that came out. There are some really nice noise reduction software programs out there that will help to clean the image a bit.
Keep practicing, it will happen. It needs to be pretty calm, and you might need to experiment a lil bit with the EV. The EV was -1.0 or maybe even more on this shot. The 8 second shots takin on this flight with the EV set at 0 were a blurry over exposed mess.
