I agree with Jimmys69,
The mix sounds really dark. Really dull, and the vocals are pretty much buried in everything else.
Yes, and it makes me wonder (because you stated this is a mix, and not mastered yet), are they planning on charging you more to master the song? It sounds to me like it already has a limiter on the output bus. Not necessarily a bad thing, but the mix does not move me at all.
The drums are ruining it for me from the start. Not the programming, but the completely sterile sound of them. The drum sound needs to be fixed, before anything. It just sounds annoyingly sterile to me.
I just don't hear the mix being anywhere near suitable for the scope of the project. I heard more possibilities (or at least enjoyed the tune more) on your mix. There was a somewhat defined stereo spread on your mix at least. Or maybe I just got lost in the drum tone, and forgot to listen.....
You do have two guitar tracks, I hear them . But do you have two tracks of the main rhythm part? I don't hear any of the goodness, that two separately tracked guitars will produce. The fact that all of these seem so 'mono', well it leads me to have a negative opinion, and subsequent negative judgement of the ability of the guys that charged you for a mix.
What do you feel about the mix that they have provided you aklugger? Your opinion is really the only one that matters. If you like it, then anything I say, is just redundant, and just my opinion. Which of course, is only worth something to me. lol.
