I liked the pizz in the strings... good call.
The hook was brilliant. I was captivated almost immediately when the piano came in. It was a very bright sound that you get used to very easily and just want to hear more of.
hehe, well I dont think this is classical. I think if you stripped everything out but the piano, and made it around 1 minute long, you could get this licensed out and it would pass as classical. Rap? it sounds nice, perhaps busy at times. If you going to have a rap it would be better if the vocals were more in the front.
Nice piano tone. The pizzicato strings took me by surprise at 0:45. After this the piano melody becomes evident, or more noticeable. Nice counter melody from the accordion sounding instrument. Interesting change around the 1:35 mark - that really was unexpected bringing in an electronic drum groove and elec guitar tune. Certainly some originality in the sound combinations used here.
