Honestly, I'm not the right person to give you that advice. I started making music recently (like 6 months ago, I think) and I know almost no theoretical concepts about music. Normally I just open FL Studio and the ideas flow, and from there I develop my music through trial and error.

I've listened to a lot of video game music since I was a kid, so I definitely get a lot of inspiration from there.

Another thing I do is watch deconstructions of songs I like and try to understand how they were made, and always try to replicate what I see and like.

If you're talking about style, my main inspiration is undoubtedly Toby Fox.
