At first glance I'd say it's got the basics, watch the leading edges though, especially on the tail fin where you have a highlight, then a dark line then the softer highlight, it looks odd, the shape of the fin is a slight curve so it should be lighter near the front.
Also there is a shadow on the radiator scoop, where is this coming from, looks odd and out of place. Hope this helps and good luck with it, nice to see something different.
