About Leonardo da Vinci

I like Leonardo's drawings.
These days I often look at them in my book and try to copy them onto my sketch book.
I have read an artist had said, "His works are too completed and not much interesting."
I think Leonardo was simply curious about nature, and he made pictures of not only correct figures of human bodies but many abstract and conceptual drawings of water flood and strange characters of people.
For myself, I also found the way of understanding the real world is very important, as well as the technique to make drawings.
I think we are lucky because you can get many photo copies of Leonardo or other old masters' drawings in good quality.
