Really stellar for your first time. It could use a crap ton more bass I dont hear much at all and I have bass boost cranked to max. A good way to fix this, or at least what I do, is to saturate and compress the hell out of it while also boosting the lows and cutting out everything below 18ish hz. Then high cut to roll off as much highs as you want, even though you are negating part of the saturation it still does wonders. (also dont use a steep filter) then use a limiter with a ceiling of -6db so that way the bass wont make everything else on top of it quieter.
The melody of this is great and the synths fit well.
