I saw this and had to pick it up, I'm not a big fan of Transformers so to speak, but I love robots, so this was a must. The book actually moves pretty quickly on how to draw, so I'd suggest this book is for people who already have decent skills, and wish to learn to draw some techniques to create Transformers. The book moves from drawing transformers, to inking, some coloring basics, and even laying out panels for a comic. Again, keep in mind that this book, I believe, is meant for people with fundamental drawing skills already. The book moves quite briskly between the chapters, but gives enough information to get you started.
I'm 25, and I really enjoyed the book, I felt a little goofy purchasing this at a local bookshop though; but oh well. We are always kids at heart, right?
