Hi hi I’m not sure exactly what you’re asking, mostly because I fluctuate between shading styles quite a bit and I’m just like “OH GOD WHY ARE PEOPLE ASKIN ME”, so I don’t have a whoLE lot of advice on shading. But since you asked I’ll give it a try - feel free to ask again if I’m not saying the right things.
The advice I’d give to someone LOOKING for a shading style is to know how to apply a mood to your pic via shading. Lately I’ve been using a much softer form of shading than I used to, because I draw a lot more “happier”, “relaxing” pictures. Shading should really compliment the mood of the pic, and here’s the two I use the most -
If I’d drawn Usagi using the second pic’s style of shading, it definitely wouldn’t have fit, and vice versa. It’s about figuring out your own “style” - what kind of pics do you draw the most? Cute ones? Happy ones? Then you might wanna go for soft shading, warm colours, ect. If you draw more serious stuff, playing around with the tips in the second pic might be better suited for you.
And like all advice in the art world, it’s never solid stuff. It’s all about playing around and seeing what works for your style of art.
