Are you, my friend, aware of the Newgrounds Audio Group on Facebook?https://www.facebook.com/groups/newgroundsaudiowip/

This is one place you can go if you are seeking for critical feedback on your music, particularly on work-in-progress tracks or compilations/reject reels.

Official description:

Welcome to the Newgrounds Audio WIP Group!

Our aim in this group is to encourage progress, improvement and sharing. Over at Newgrounds, the Audio Forum can get cluttered and seeking advice on a track per track basis can be tedious waiting for someone to give you a review. Overall tracks can be lost and threads on single tracks isn't permitted. 

Here, we have a straight-forward approach where we can get the approval, interest and most importantly feedback on all our tracks well before we release them on Newgrounds, or anywhere else for that fact. 

We also promote compilation tracks of up to 15mins. What are compilation tracks? Well let me explain. No doubt as an audio creator you have loads of tracks you start with great intentions, then for some reason be put off it and leave it to die a lonley death. But what if you've abandoned something which is seriously good and you don't know it, maybe it's worth going back to? A compilation of unused tracks can be uploaded on a linked Facebook SoundCloud account! This let's us listen through the compilations and create comments on specific points of the tracks where we hear potential, or if it's a WIP track, problems.

Here we promote group inspiration by sharing WIP and "Failed" tracks. With a strong passionate community about audio, there's plenty we can do for each other.
