good to see my stuff in use
but the 2005 Ford Mustang is way to distinct to go on a car like that... actually so is the skyline front you used. I suggest changing the two up some, at least use different brake and headlight designs.
Right now it looks like something driv3r would do... They've got stuff like '67 Camaro fronts combined with '67 mustang fastback rears... they're believable, but it is kinda akward seeing that stuff, just because the vehicles look so much like replicas until you see the full thing, then it's like ... woah .. heh
anyway, for some good ideas on how to vary a car up, look at the way grand theft auto makes its vehicles different from the originals.... like the 1974 Buick Riviera and the Idaho are a good example... the brake lights on the real car are very distinguishable, with almost a chrome 'grid' on them... gta kept the general shape, but the brake lights make it harder to tell what the car is... Same with the front end. The headlights on the real vehicle are 4 round headlights, with a turn signal that's separate from them, yet the headlights on the gta model look more like those that would be on a 1988 Chevrolet Caprice or something
just some ideas... not sure what your plans for this are, like whether you're going to model it out in 3d, or just an interesting thing to look at... but yeah...
