The intro's too long.
there's too much reverb on your voice.
The piano roll - doesn't quite work - too many grace notes & I'm the king of grace note abuse.
The bass is too furry.
I'm non musical in the ear department but a whole bundle of elements seems to have been sued regardless of key.
Now, it could be me & probably is.
I'd hate to pay royalties for all of the cr elements in this.
Back to basics though the bass in the backing is too woolly and spread to widely across the stereo image - too many effects I think.
Your voice is wrapped up in the safety of reverb and sounds soft, ineffectual, there's no presence to it. You need to tweak the EQ a bit if not remove the cotton.
Create a structure - the penguin voice/girlie bits seemt o offer the oly structure to the piece.
the streamer on reverb nation isn't too flash so some quality has been shaved off.
Nice editing, and soe smooth elements though.
Sorry, I've not seen any of the modern Batman franchise flicks - not into the caped crusader since the TV series ended.
