Pros - I think you accomplished exactly what you wanted to. As for me, I can appreciate it, but have a hard time enjoying it. Accent is pretty cool
Cons - Doing the doubling of the vocals the second half of each phrase is, i think, overused and doeesnt do much to seperate yourself. I thought the bass coulda kicked a bit more...but maybe you didnt want that.
The Handclaps were: Very fake...but obvious enough that it wasnt like you were trying to get away with anything. I think having SOMETHING beat where the handclaps were is a good idea, and in a re-mix id repace the handclaps with another sound.
Summary I wish I could give something more constructive than I have, but overall you kept the flow going well and sounded like you knew what you were doing.
