it must have something to do with the resolution i set it at in order to post them, as in the two originals, all the lines are smooth. Yeh if you see the original, you will see that i actually used it very little, i used my own knowlege of lighting and reflectivity to add such reflections as clouds. in fact i will post the original or better a link. so i can show you the windows, (since many of you think im obviously lazy, read ahead and then youll know that i am indeed not)
Here it is,

resolutions is 1024x768 and lets not forget that whatever resolution the original image, the same resolution will be applied to your vector.
The reason why the shadoes look a bit scruffy was because they are. i used the Paintbrush tool to create every spec of Shading and reflections (apart from the Headlights, rims and windows) so i was trying to achieve reflections, but im having a tough time finding a Vectorising method that suits me in terms of realism and cartoon re-creation.
