Jeff, if I can give any advice about building models, it would be to stop comparing your work to others, especially someone as skilled as Harry. I don't know if you'll ever achieve that level of craftsmanship but I know I won't. I just try to learn from them and make as few mistakes as I can. What winds up on my bench as a finished model would be trash to some builders but I'm learning, having fun and can see that what I'm building now is light years from what I did as a kid. Remember, have fun!
PS I have the Lindburg 1:16 Stutz and Mercedes racers in my stash. I'm not much of a scratch builder myself but I do want to build both of them some day. They do look easy. How detailed they'll be is questionable.
