Different menulis style in the same series

I thought I'd write a story idea out as "Being" different characters, having the style be in present tense and detik person while having different parts with different characters being the one in first person. But I'm getting tired of it, and I can't be bothered to ubah all I've got so far, it's too much.

So I was wondering if I should just go back to the normal menulis style for the selanjutnya story I have planned, which takes place about thirty years later. I may not even post my first story, that one being a warm-up instead and giving me lebih of an idea of the backstories of some of the characters and events involved atau mentioned in the new story I plan to write. Does anyone think this is a good idea?
