BTW if anyone has some advice on actually properly mastering I'd welcome it
EQ + Compression basically. You can go for days tweaking and listening back on every speaker you can find. But there are tools you can use to cut that considerably. Souncloud have one built in, and there is Landr (which is pretty good, and free at its basic level)
