Though I will always prefer the original Tears for Fears version of this song, you did perform this well enough.
You have a lovely singing voice, btw.
Piano's too muddy?... Eh, too much reverb. You should try to bring it out more. Then again i dont know much about ambient.
About the vocals... Just feels like your holding back a little bit. Idk, can't put my finger on it. Maybe sing it 2 keys done, or up.
Kinda like the last part a bit, interesting.
But i guess you shouldnt have submitted this on ambient! You should have posted it on classic or on miscellaneous.
