Here's a new book on sketching from Page One Publishing.
Ruzaimi Mat Rani authored this book, as well as the earlier Sketching Masterclass book.
It's a 208-page paperback dealing with one point perspective specifically. So there are enough exercises to make anyone proficient. The lessons starts with drawing simple geometric boxes and placement. Then it moves on to more challenging ones like drawing curved surfaces and irregular shaped objects. The examples are all step-by-step illustrations.
Great book for those who want to practice more one point perspective drawing.
This book should be available at all Page One bookstores and Kinokuniya.
There's a giveaway contest for One Point Perspective on the blog until 28 Jul 2012.
