Well, it sounds fine. I "master" my songs myself so you're definitely not alone.

Advice:

- The sub bass could be a little stronger. I know it's easy to mess up the mix with an overwhelming sub, but I don't hear much sub.
- The vocals and field recordings (birds, breeze, chimes because I don't know what else to classify them as) shouldn't be quite so loud, as they can take away from the melody sometimes.
- The piano sounds a little "flat", I don't know why but I feel like there's some part missing. Maybe a little lower frequencies. If you took some out to stabilize the mix, I can understand.
- You used the same melody a lot, especially in the first half of the song. There could be just a touch more going on as for variation.

I like this song. I like how you blended electronic music with the Halloween vibes.

Since you got some feedback, I'd suggest giving some to a few producers here who haven't gotten any yet.
