Hey that is not a bad shot at thiswhole modeling thing at all. I think that we all have to start somewhere. keep this project going, some good things could come of it. I am new at this whole modeling thing too. I have found that the more I work with it, and get the basic concepts of the program down, the better I become. I have also found that it is much easier modeling with a blueprint of what you are going to create. Keep up the good work, and if you have not already done so, I would recomend working with some more tutorials, they will help you work with understanding the forming of the wheels, and seats, all of that stuff. I model in mostly using polygons. any ways good luck with finishing your creation, you have a great start so far!!
