Despite the book being entirely in Japanese, it has amazing step-by-step tutorials that are easy to follow along with without reading the text. The pictures show you how to take each illustration from one point to the desk, showing you what tools in CSP, and even what exact colors to use by provide the HEX codes. Even though the book is for CLIP STUDIO PAINT, I've followed some of the tutorials for watercoloring as well and the gem tutorials are definitely my favorite. Overall, I wish I could buy more books like this one!
