not bad for a first model. One thing you could try even on this one is bare metal foil . it is an adhesive backed chrome foil used for thing like window trim ,scripts,and anything else that is a little too narrow to paint .you basically stick it on the trim ,burnish and then carefully trim with a sharp hobby knife. Is your tubbed dragster going to be a large scale like this one ?I think scratch building may be a little ambitous but you gotta start some where.although building a few more models out of the box and learning some solid fundamentals would go a long way . specific questions will be answered more often than extremely broad questions because there is so many different ways to accomplish building a model . good luck and have fun!
