**EDIT** Guys you don't have to do this lmbo. It's just what I do in my own art. Quit being so salty about it in the comments smh imagine getting upset over an art tip from another artist Everyone's art styles differ from person to person, but here's a tip I learned from my own experience: Try not to rely on airbrushing for shading. It ends up looking muddy or hazy, and can affect your work for the worse. Instead, try to add more crisp edges for shading. It makes it stand out better and can make it really pop. I know the example used here isn't the best but I whipped it together for a friend. If you're doing lighting, draw the crisp edge light first and then gently add some airbrush strokes to create the effect that it's glowing. Don't overdo it or it'll be too bright or too muddy. In some cases it's fine to airbrush for shading, if you want to create haze or shadows. But if you're trying to make shading for an everyday scene (standing outside, etc.), it may not be the best choice. It takes some time to learn if you're not used to it, but it'll help improve your own art in the long run. Hope you found this helpful :>
This project doesn't explain or show my personal art process very well so here's a good example of how I use this trick in my art: https://scratch.mit.edu/projects/1169244568
