I'm not a big fan of dramatic orchestral JRPG music, but the two tracks I heard for this game are great. You're going for a homage to classic RPGs, right? Well you've nailed that, but not in the really "retro" intentionally bad way, instead your soundtrack is legitimately good in its own right. Because of this I really think you should use the music as a big selling point. Anything original in a RM game is such a boon for making people interested to play it, and as I've seen you're using RTP-style graphics, make sure to capitalise on the music as a unique selling point. I'm sure you're probably fully aware of this, but definitely play to your strengths, especially where original content is concerned.
