where are the reflections? where is your light source? the shadow tells me it's from behind and low... so it doesn't make sense that the "rendering" shows a much lighter surface around the front headlight/fender area than the back, which would be catching all the light, but instead is dark, in fact, second in darkness only to your undercut areas. this does not make sense.
design is ok, but proportions are silly. this suggests the DLO is no bigger than half a wheel. 9 inches of glass at its widest point? Also, in a side view, you see the front and rear windsheilds - not just the A and C pillars.
keep at it. try to work on smoothing out your gradations on the body with brushes or dodge/burn or whatever you're using. and dropping in a hotspot or two with a highlight will help it pop.
