You’ve got a nice lifework style Sketchstone. I think that second rendering style is working much better for you in the car post above. The form is reading much better I think. One thing I notice is that sometimes your lines don’t quite connect. As a result the line sometimes starts to trail off a bit too early making something have the appearance of drooping slightly. When you draw try to extend the line well past the intersection. This way when the line trails off as it naturally will, it will still finish the form in a strong way. You can always erase these trailing edges after.
