I love microfiction because it is the closest to perfect you can get (For sale: baby shoes, never worn.) and you can experiment easily. I love BOFURI because the writer took it easy, wrote a small amount each chapter, and captured happy little moments. Apparently, neither I nor the internet can agree on what differentiates Eastern and Western styles. I think it would be good if you focused on understanding why you like the things you do and incorporate that into your work. Then you can develop your own style. You are already starting to do that by dissecting what makes something moe.
I haven't sorted out my motivation to write. I know that rereading my stories makes me really happy, which is good because barely anyone else reads my stuff. Maybe it is better to write for yourself than for validation from others, but it was a very lonely experience for me. I always had doubts that I was a bad writer, especially when people didn't want to even take a literal minute to read one of my pieces. People say I'm lazy and untalented because I don't write very much and because I mostly stick to being cute and funny. It hurts.
My style is to mostly write dialogue, make it natural sounding. When I brainstorm dialogue, I will imagine the characters lounging around and chatting, then boil it down.
I make it a point to describe as little as possible and when I do, to just say what it is. I don't like rote five senses writing, sterile evocative language, big words, needless description that leaves less room to for the reader to imagine the characters and surroundings. If I absolutely need to describe thoroughly, I pretend I'm gossiping, bragging, threatening, mocking, then convert that. This type of behavior isn't healthy, so that's why I do it sparingly.
When I'm being serious, I to try to write what I know that other people don't, or at least what I'm interested in. This is more important than world-building. Police in a Pod, Cells at Work, Uma Musume do not need much world-building because the details of expert knowledge is a world unto itself.
It took me about a month to come up with this toolset for myself and people don't take it seriously because description and world-building is much more important to them than me. I'm also worried that this system has made my writing formulaic. Post too long. Click here to view the full text.
