Oh boi, this feels a lot like the classic Megaman soundtrack, which is a great soundtrack, just need to add some drums, and bam! [imo ofc] However, there are somethings off with your song. First, I can actually hear some distortion when something is playing on top of the bell. Like static or something like that. It's either the audio quality or there is a problem with your mix. The song was a bit repetitive at times, just that it's playing in different orders. Maybe change up the melodies once in a while?
Also, just a few suggestions tho, maybe you could try panning your instruments to give it some extra details? Take the bells for example. You can try to make it pan left and right, like something is moving? I don't know, it's up to you. You can also try to give it some extra details by adding a few more stuff, like something to do the chords [ex. choir, pad, etc.] and some sound effects [ex. risers] to make it more interesting.
Overall, I really get the classic Megaman feels in this song, but I think it needs a bit more detail and also polishing in the production value.
