You are just one coat of primer from having a really " finished" looking car. As a matter of fact, I remember in the late 60's/early 70's colored primer was the cat's ass for low riders here in L.A. Check with your local paint person about color tinting primer and see what you come up with.
Also..... now this is not a comment about your car individually (God knows that I don't have a T yet and probably won't for awhile, but I do have a good eye for proportion and a good feel for whats right on a car), but I think that getting the exhaust parrallel to the ground instead of pointing down hill is much more pleasing. Also, perhaps extending the pipes out past the rear end (maybe to the edge of the rear tires, either over or under the rear axle) would be kind of dirt trackerish AND easier on the ears.
Just my humble opinion.
A "finished" car is not hard to complete. It doesn't need chrome, fancy paint or outrageous tars. Just a visual feeling of completeness and attention to detail.
And of course you can s**t can everything I have suggested and enjoy it the way it is
(Do look into the primer/tinted primer thing though)
