The opening bell sound (or whatever it is) needs more "ring" to it, in my opinion. Maybe some FM?
about a minute into the song, it begins to sound very muddy. it sounds like several synths are all playing within a single frequency range. You might want to apply some filters, maybe some highpass filters at some point. (Filters can totally change how a synth sounds. Don't overlook effects. I made that mistake early on)
I'm guessing the BPM is 120, right? the guitar (I guess it's a guitar) that comes in could probably be replaced with a more etherial-sounding synth. It's also a bit muddy, which ties back to the earlier filter comment.
I have to say, it does get repetitive, but I do like the strings at 1:20. opens up the upper frequency range.
Overall good job. Better than my first, second, third, 70th mixing attempt
Needs work, but this has potential. keep working on it!
Edit: A little friendly hint: if this is a mix you feel like you will keep working on, mark it as Work in progress. If you plan on submitting it someday, you will want to keep it at WIP status until you feel it needs to be judged by a staff member, in which case, you change the suffix to Mod Review. When you feel like the mix is at it's pinnacle, mark it as Finished, whether or not it was Mod Reviewed.
I plan on watching this thread! Good Luck!
