Personally dig the color choice and the concept of stretched fenders on a first gen. I think there's a right and wrong way to do it, and you can only tell by seeing the car in person; pics can skew proportions. A little 'fat' is good, exaggerated = bad. First time I saw it on a 69 @ Cris' shop I was blown away how good it looked.
Soooo....hard to tell from the pics, but looks good so far!
Edit: IMHO, side skirts would be too much. I also feel - from the pics- your front spoiler is too 'swoopy' in front of the tires. Much respect for all the hard work and artistry of your design and I'm only trying to give you an honest opinion.
