I am sure we have all been there
One mistake of newer home recorders is that they tend to "overdue" things. When they EQ, they dont just reduce a few dB here or there, but they tend to CHOP off an entire frequency range. Then when they add reverb, instead of going for a natural sound, they end up singing in a auditorium. Things like this are tough to over come because you always think adding these "effects" will make your msuic better. But often, less is more.
I heard once that the secret to putting makeup on is to make it look like you have nothing on at all. Often this "idea" can transfer over to editing and mixing. When you listen to many recordings, you know there are these effects applied, but they are done in a method to make the music still sound pure or realistic. Often less is more.
