Using Coloringbookmaker.art for practicing watercolor

You can practice using watercolor by printing a photo (free usable photos from pixabay) and adjust the sensitivity to light and line thickness to light, and leave most of the page with just a few hints of the subject. This way, it will show you where the darkest values are (black lines) and let you focus on using different colors instead of stressing about form, shape, proportion and shading. In this example, I used watercolor pens. I have not seen a difference in quality when it comes to watercolor pens, the cheapest is the same as most expensive, so I would save the expensive products for things that have a massive difference in quality, like pastels.
