This is a neat start! Your line work on that plane is very appealing!
One thing to keep in mind is composition. Right now two-thirds of the entire picture is just the sky, and even that is just one single color. The thing your eye is immediately drawn to is that big, empty sky, which means the viewer isn't seeing what you want them to see.
For this particular piece I think it would have been beneficial to make the plane take up most of the canvas, or at least crop out half of that big, empty sky. That, or add some interesting cloud shapes there to at least add some interest.
Otherwise though, not bad at all! The plane itself is really well drawn!
