I've always had lots of different styles:
This is just a few. I tend to create a new art style for every new project I start, even if it's just a character design series. It's part of the fun~
What's more, I'm happy with all of them. I'm happy to have them all, and to have the possibility of inventing dozens more in the future. I don't feel any pressure to "focus" or choose one over the others, and it's always felt kind of weird to me that most artists seem to feel the opposite.
It's not like my comics will get muddled; on the contrary, having so many different techniques available to me helps me avoid introducing alien ones in a comic that already has an established style: if I get a yen for realism, I just take a break and go work on a project that's been assigned a realistic style, and so on.
Apart from the fact that my galleries tend to look like 3 or 4 artists were contributing to them at once, I don't see any downside to being an experimenter. ^^; As an artist, I feel like it's important to do what you want to do. Don't close yourself off from new experiences just because you feel like you "shouldn't". Life is too short~
If there's any element that's nearly always present in every new style I come up with, it's cel-shading techniques (of varying degrees of complexity). Even the fluffy owl-child in the bottom center was just done with super-detailed cel-shading, for the most part.
This is partly due to the limitations of the digital art tools I have available right now, and partly because I'm just a very impatient artist. I want things done fast; I want my ideas out of my head and on a screen as quickly as possible. I can't imagine being one of those artists who spends weeks or even MONTHS on a single piece. I'd die. I'd kill myself. I'd crack my laptop over my skull and end it.
However, I do occasionally dabble in more 'painterly' things, just because I want to have the option. It's actually a pretty speedy style when I do it IRL with real watercolors, so every once in a while I set about trying to find a way to replicate that digitally:
