Pretty neat. The overall shape looks rather good, although the design seems to be a tad blocky at spots. The colour scheme isn't awful, either; the otherwise lonely silvery tail fins are quite nicely paired with the grey lines on the windscreen.
If you want to improve it, however, here are a few suggestions.
You might want to do away with some of the trans-light blue bricks; they look somewhat overused now. Some black or light grey greebling instead of them might look nice. Greebles could also be put on the blocky, holey spots on the nose.
In addition, the side panels don't really seem to fit with the overall style with the many studs and sharp lower edge. You could try to brick-build a more solid and perhaps more greebled substitute. Blue or light grey highlight may not look bad on it, either.
