so I ordered a nature sketching book from amazon called nature anatomy, by julia rothman:
it doesnt really teach you how to sketch but it contains nice images and the authors uniqe style...
It gave me inspiration to doodle some myself...
as you know, I have been trying to auto-learn to draw for a while. I still dont have the confidence to draw from my head, but this book gave me inspiration and It made me almost fly free like a bird...on my way to freedom:)
