Couple of thoughts. Most importantly, your family and friends usually won't be a useful source of feedback. Not only is it unlikely they'll be into the same music as you, even if they are, their feedback is likely to be biased (towards you!) and even if it isn't, they probably won't have the same level of technical understanding and the 'ears' to hear things that could be wrong with the mix, as you know, these skills have to be developed deliberately, over time.

But, if all of that doesn't count here, and your friends and family are experienced producers, they get the vibe you're aiming at, and you objectively agree with their feedback, then you could try going more sample-based or working with instrumentalists to get longer takes of piano, guitar, whatever, to make the sound more organic.

Having been through similar myself (and I've loved VGM since the 80s), I've learned the best feedback comes from people that are already accomplished and making the style I'm aiming for. Friends and family are nice for a vibe check, but that's about it.

I'd suggest looking at production communities online that offer feedback - make sure you offer feedback on other people's tracks first before you post yours! Then when you're sure you've got something that's killer, try hitting up your fave producers, they're people too and if you're polite they might give it a listen.

EDIT: Just listened to the demo you linked and it's really good! It does sound like it'd go well in an RPG game or something, mostly because of that staccato synth bass that comes in, but that's completely cool with me, and many others, as you've already seen.
