Looks good Tom. Maybe whatever isn't making you happy will grow on you. If you're going to paint it evenutally, it may look better with paint? What about the look don't you like? The amount of tire filling the rear wheel well? The skinny fronts?
I'm not sure what you're going for, but most of the cars i've seen with those running board aprons (is that what they're called?) from back in the late 40's had taller tires all the way around, and definately in front. I don't think most of those cars in the pics had white walls either and they looked cool.
I don't know if you've ever been to
www.ahrf.com, but in the "photo gallery," under "hot rods" then under "roadsters" there are quite a few pics of good looking 28 roadsters with aprons. May help inspire. Its a great website.
I got the authentication failure too.
