Can you guys determine the problem just by listening to the RAW unmixed acapella?

[Mr Music]

Hi guys...I totaly hate my RAW recording...
I think the main reason is because its the room problem...
i tried everything and I just despise it...
if i were to post the acapella, would you be able to tell me what is needed?
i already made a booth and still it sucks...
thanks

sometimes its too blocky, sometimes its not jeeez
