Too much reverb, it sounds like specific sounds are clashing together and making that 'muddy' effect with using too much reverb, did you reverb the whole master track or each individual instrument?
Would love to hear a longer version, I can't really review this that much because its very short and just repeats.
Thanks for taking the time to reply in regards to too much reverb I was taking this opportunity to use my own created Impulse Response Samples, these are a way to create reverbs of any room using a Sine Wave sweep, Deconvolver and Convolution Reverb this process it's self can be a little difficult as microphone and sample placement in the room are everything. And not everything has Reverb just the Keys to create the reverb effect I wanted and the Guitars because they where DI'd with my 003Rack+ using the Plugin Eleven so I added the Convolution Reverb was required to add to the "Real space" Sound I was going for, I used a Impulse Response of a Venue Space The Arches in Glasgow, Scotland. Old Vicotrian Railway Arches converted to a Venue. As for the mud I personally don't see this as mud little bit of distance with some of the parts If anything I think the Mix lacks between 500 - 1kHz. The Balance you are right could have came to more of a conclusion as that is something I am now not that happy with. Longer Versions of this and any other of my material on here are available for projects because as you should know anything that is posted here is under a creative commons Licence and I like to know where my more stuff is being used and is here for sample projects, I also create Other Works and Full Sound Design for film and Games.
