I think that a lot of people can relate to this. When I started drawing I underestimated the importance of shading. I used to draw a lot of manga and used the typical shading technique that you see with the old style of anime. Animes like Pokemon. The ones where there are little differences in colour to show the shading. Not realistic at all, but I wanted to make more and more realistic drawings, but failed miserably.
After years of experimenting, I learned that shading comes when you draw the textures. They are all the shading you need. You can see that with my sketches. I didn't do any shading, but I recreated the texture of the wings on the insect or the fur on the dogs. Should I make a video or tutorial on drawing shades with textures? What do you guys do to make shading on a drawing?
I didn't make this drawing, but it shows the different textures that you can use.
