Overall, "Sketching Techniques for Artists" by Alex Hillkurtz is a valuable resource for artists looking to improve their sketching and drawing skills. The book provides a comprehensive overview of various techniques, from observation and gesture drawing to value and shading. While it may have some minor limitations, the book is well-written, engaging, and suitable for artists of all levels.
