Your pictures present problems for being mostly blurry, dark and killed by motive issues. Not always do these apply simultaneously to all of your pics, but I believe you might not be able to solve all these issues. You´ve got some centering problems on some pics, and some size problems in others as well. Be sure to edit your images within the 3:2 and 4:3 accepted frame ratios.
I´ll second what Martin previously said: Keep practising. His tips are spot-on, maybe you´ll need to shoot in broad daylight and focusing first in framing the whole aircraft and leaving close-ups for when you get more experience. Also, review your camera settings, because you´re having blurriness in almost all of your pictures, so I thought that maybe you were shooting with a slow shutter speed.
And at last, when you post, try to show some few shots, because it´s better for us to view up to 4 or 5 photos and not a whole 15-20 bunch. I believe you´ll receive more and quicker feedback if you post fewer shots.
Hope it helps.
