I searched sketchbook and I found these lovely pages. They're all so beautiful! Your whole sketchbook must be beautiful to they eyes. May I ask what you use to color? It looks like watercolor but using watercolor on sketchpaper wrinkles it so I'm asking.
For a sketchbook this is very advanced stuff! If your sketches looks like this I wouldn't mind seeing more of it
I love how the fishes swims away from the green haired girl. I also very much enjoy the sketches in the upper right corner. The boy(?) with the "Milk" jacket has such a pretty expression as well as the lady on the side!
