Hi Carlo,
Zedalist, Thank you for the valuable information.
I think its very important to have good balance between accuracy and artistry, there are time it is necessary to be "inaccurate" to be beautiful.
By the way, I just visit your website and I LOVE IT!
Very happy to see top quality blog!
BTW, your wife does beautiful ground work. I'm also very lucky to have a woman who is involved in this hobby.
Please keep up with the excellent work!
