Thanks guys for your great responses. On top of my Ambient stuff, i also played in a death metal band for eight years and i now record metal bands in my home studio. I do have experience in the audio engineering field but i know that mastering is something that pros should do and i am aware that noobs will tend to "overmaster" or overlimit their stuff.
Not sure if any of this is helping the OP
Julio don't worry this is helpful. I try to approach everything with an empty cup and see what i learn versus what i already know, you are a great artist and helpful dude
I just really feel that if i get a professional mastering job on my tracks it could open up future business with my ambient career. Thanks again for the links, i trust in who you guys go to!
