clockwise from top left:
-ellipse is off, front of car skewed right
-pretty good. think about line quality
-use a circle template
-assymetrical rear window, one or both ellipses off
-too narrow and ellipses off
-(tiny one)ok
-(bottom) draw a center line and center stuff. You tend to pull the far side of the car to the front.
-good, interesting design
-skewed badly to the right. ellipses too
-something odd with the front right fender, stuff skewed. again, center line
you would do well to pick up a set of curves, sweeps and circle/ellipse templates and to draw the center line in order to more easily visualize the placement of design elements.
That said, I have troubles with a lot of those problems too and would like to wish you the best of luck.
I'm in Trans too- do I know you LOL?
