Hey, let's not be mean, let's be helpful. This guy says he's only 16, so I'm gonna guess he doesn't have a college degree or years of experience under his belt like some of the rest of us.
First off, where's your sketches? Did you just model this out of your head and not have anything for inspiration or even a blueprint? That's never going to work. Let's see what you were shooting for and then we'll be able to comment on the model.
You've got to draw and draw until you get that good sketch. Get the crappy ones out. (Funny how the crappy ones always come first.)
Once you know what you want to do, draw the car in top side and front views to actual scale (1/18 in your case) so you can make templates. At least then you'll know if you're making what you sketched out.
Then you need some work with your modeling skills. Craftsmanship is huge when you're tring to convey your ideas to someone else. I can't really tell from the pictures, but it looks like you might have done most of this with your hands. (still quite an accomplishment) You should learn how to use some modeling tools though. Rakes and steels are the only way to get really smooth surfaces. Mastering them and learning to see what a surface is doing is the only way to a show quality model.
You might think about making your next model a little bigger too. Modeling tools take a bit of room to work and it might be easier to see what your surfaces are doing if they're a tad larger.
Lastly, Let's not photoshop on top of our clay. Neat thought, I might have done it myself when I was 16, but it's a little cheezy. Get your hands on some black studio masking tape and mask those windows and features proper!
I guess this could come across as me being a little harsh and I don't mean to be. I want to be friendly and helpful! I'm just pointing out what I see. I'm in the process of making a model right now and it's hard work. A tall stack of sketches is step one though so let's see what you got!
you need to start with a single surface, like the roof or hood of a car. Use the correct tools, rake the surface to the basic shape and remove high spots. Then steel the surface to a smooth finish. Learn to see high and low spots. You can work the clay with steels till it is shinny, once shinny you can see reflections and really evaluate the surface and then learn to control it.
You need to work on the cabin. no one wants a sports car but have a tiny space. take a wet sponge and gently run it over your clay to smooth it out. other than that good work! I hope when im your age ill be doing clay modeling! @F1racer- Ho Shiz! Some nice concepts you got there!
