i actually thought at first glance this one seemed a little better then the chevelle. but when you go back to the main readers talent page, the second entry from the very top is a drawing template for 3d views, it has 2 wheels already placed and has a very light box..try printing it out and drawing from that. I havent drawin in 3d in forever and recetly printed off two copies of it for myself and it helps. It isn't easy getting used to the new view when your trained to a different one but after a few drawings it should help.
Also another trick i learned to check proportions, once you draw it, scan it on to the computer and lok at it, see what looks off..then fix it on paper. Or, you can also just hold the page up to a light and look at it through the back, this will deffinetly point out any flaws, i do it all the time.
