Sketches are important, because they are like exercises, and with them we can create simple or complicate drawings that let us to improvise or check if an idea is useful for a comic or for any kind of image. Is a great way to create new characters designs, so as any kind of designs, like machines, places, architecture, etc. But in this section there are not only "sketches", like the image on the right of this page, there are some images that are finished, but they are some ideas that, maybe, will not be used in the actual manga or anything else. Again, some of them are just exercises, more or less complicate. in the future, I will put some images that have passed by different processes, to finally became a finished image. If you are learning how to draw, maybe you will find them useful.
