Looks cool man, and don't worry about critisicm, it will only make you a better builder, I bet the next one you do will look much better. I am sure he didn't say that to make you feel bad even though I think he should have gone about it a little better.
I for one consider myself more old school, your choice of rims looks cool but I personally would have gone another route but hey, this is how you and some other people like it and that's what matters.
Color choice is also beautiful even though I would have preferred a non metallic color but again, it does look great. One little word of advice, try working on your panel lines, they really do make a model stand out. These are little issues that we all here learn with time and if I tell you that it all looks perfect, I don't think I would be helping you. You have great potential to be an outstanding modeler. The engine bay by the way? Looks phenomenal!!
