You just have to do what you know will make you the most happy with the outcome.Ah, now I see it. I can live with some small details wrong, but the shape is one I wouldn't be able to.
Looking at that overlay I think it might just be easier to design a new one from scratch. I think it would turn out better and be more accurate, plus I could add better interior parts than the Gambody one. Got me thinking now!
I think most everyone here will tell you that they start a project that seems like it shouldn't be to hard....and then doing so much to it, that most is changed by the end, but they always turn out so great.
My MPC Falcon I'm working on. Was just going to do a quick repainting...and here nearly 4 months later still adding stuff to it. Mostly finally working on the weathering now, but its turning out far better than I could have ever expected.
